Last Updated: November 1, 2025
This End-User License Agreement (this "Agreement") is a legal contract between you (the "Licensee") and Woodhead SAS, a French société par actions simplifiée (SAS) registered under SIREN 992 285 528 with its registered office at 17 Rue du Maquis, 86000 Poitiers, France ("Licensor").
The software known as Natsura is owned by George Hulm and Feike Postmes (the "IP Owners"). Licensor is authorized to grant end-user licenses, collect payments, provide support, and enforce this Agreement on the IP Owners' behalf. Ownership of the Software is not assigned to Licensor by this arrangement.
By installing or using the Software, you agree to be bound by this Agreement. If you do not agree, do not install or use the Software.
"Software" — the Natsura application, plug-ins, updates, SDKs, presets, templates, graphs, scripts, and related materials.
"Customer Assets" — works you create using the Software (e.g., 3D models, textures, materials, meshes, rigs, graphs, renders).
"Commercial Use" — any use in exchange for or in expectation of compensation or other consideration (including ad-monetized content, sponsorships, or barter).
"Packaged Asset" — an end-user-consumable asset (e.g., meshes, rigged meshes, geometry rigs for DCC/game engines, textures, materials, runtime graphs) that does not include Toolkit Components or source artifacts enabling regeneration via the Software.
"Intermediate Files" — non-final computational artifacts intended for rendering/simulation/downstream processing and not directly usable by end-users without the Software (e.g., sim/scene caches, USD/IFD-like exports, graph caches). A USD or similar file that is directly usable in a DCC/game engine without Natsura and does not enable regeneration in Natsura is treated as a Packaged Asset.
"Toolkit Components" — any part of the Software or extensions for it, including nodes, operators, graphs, presets, templates, scripts, plug-ins, header files, or SDK elements.
"Derived Dataset" — a dataset whose primary value is substantially composed of Customer Assets or artifacts generated by the Software.
"License Models / Tiers" — Apprentice, Indie, Pro, Studio, Enterprise.
"User Seat" — a Seat assigned to one named Authorized User and activated on one Computer at a time.
"Device Seat" — a Seat assigned to one Computer (not user-bound).
"Authorized User" — an employee or Contractor of Licensee, authorized by Licensee to use the Software solely on Licensee's behalf and bound by terms no less protective than this Agreement.
"Contractor" — an individual or entity engaged by Licensee to provide services to Licensee, under confidentiality obligations and at all times under Licensee's direction and control.
"Affiliate" — any entity that directly or indirectly controls, is controlled by, or is under common control with a party, where control means ownership of more than 50% of voting securities.
"Funding" — capital available to Licensee's business from equity, debt, grants, advances, or crowdfunding.
"Payments Domain" — billing, invoicing, renewals, cancellations, delivery, chargebacks, refunds, and transaction taxes handled by Paddle as Merchant of Record.
"Fiscal Year (FY)" — Licensee's last completed accounting year; if none, the trailing twelve months (TTM). FX: Non-USD figures are converted using the European Central Bank daily reference rate on the FY close date (or TTM end).
"Computer" — a single physical or virtual machine instance. For cloud instances, each VM/instance (including any clone of a golden image) is a distinct Computer.
"Model Training Activities" — training, pre-training, fine-tuning, evaluation intended to improve models, dataset creation, synthetic data generation intended for model improvement, or any activity where Customer Assets or Derived Datasets are used to produce or improve a model.
"Substantially Similar Model" — an AI/ML model whose primary purpose is to generate or procedurally construct foliage/vegetation assets or runtime graphs that are materially substitutable for core Natsura functionality.
"Extension" — a plug-in, script, preset, template, or integration developed by Licensee that interoperates with the Software but does not include or expose Toolkit Components.
"Competitor" — a third party whose principal commercial offering includes tools for foliage/vegetation creation or closely substitutable technology.
2.1 Ownership. The IP Owners retain full ownership of all intellectual property in the Software.
2.2 Authority. Licensor is authorized to grant licenses, set prices, collect payments, provide support, and enforce this Agreement on behalf of the IP Owners. If the IP Owners later transfer ownership or licensing rights to Licensor (or another successor entity), all existing end-user licenses remain valid under their original terms. Any such transfer will be notified in writing (including email) to affected licensees.
3.1 License. Subject to payment and compliance, Licensor grants Licensee a non-exclusive, non-transferable, non-sublicensable license to install and use the Software to produce Customer Assets within the applicable Tier and Seat limits.
3.2 Installations & Movement (rolling 365 days).
3.3 Non-Concurrent Use. Interactive components may be used by one individual on one Computer per Seat at a time.
3.4 Cloud Instances. Node-locked installs are permitted on cloud VMs. Each VM/instance (including any clone of a golden image) requires a unique activation bound to a per-instance fingerprint. Carrying an activation across cloned instances is prohibited. No pooling or sharing.
3.5 Activation & Offline Use. Initial activation requires Internet access. Thereafter, Seats may run offline subject to periodic revalidation. Failure to revalidate within a reasonable grace period may reduce functionality until reactivated. Licensor does not guarantee an offline activation method at this time. If online activation services are permanently discontinued, Licensor will use commercially reasonable efforts to provide a workable path for compliant perpetual licensees of the affected Major Release (e.g., escrowed offline keys or a final "offline build").
3.6 Location of Use. Use occurs where the Computer is physically located or, for cloud instances, where the compute resources run.
3.7 Seat Caps & Floating. Seat caps and eligibility are defined per Tier in §4. Floating/network licensing is not available at this time and may be offered under a future Enterprise agreement.
3.8 Reassignment (rolling 365 days).
3.9 Contractors. Licensee may permit Contractors to use Seats solely to provide services to Licensee. Licensee remains responsible for their compliance.
Single-Tier Rule: Licensee must select one Tier that applies to all Seats (Interactive and Headless/Worker) across Licensee and its Affiliates.
4.1 Apprentice (Free; Non-Commercial). Non-commercial use only. Max 1 Seat. Node-locked only. No guaranteed support.
4.2 Indie (Revenue or Funding < USD 100,000). Commercial use permitted. Updates included during an active subscription. Standard support. Up to 3 Seats total.
4.3 Pro (USD 100,000 – 1,000,000). Commercial use permitted. Updates with active subscription. Standard support. Up to 3 Seats total.
4.4 Studio (Revenue or Funding ≥ USD 1,000,000). Commercial use permitted. Updates with active subscription. Priority support (faster SLA). Up to 6 Seats total.
4.5 Enterprise (Custom). For organizations requiring more than 6 Seats, bespoke SLAs, or other custom terms. Custom pricing and terms apply.
4.6 Tier Compliance. Thresholds apply on a consolidated basis across Licensee and Affiliates; measured against the higher of last FY or TTM (see §1 FX). Headless/Worker Seats count toward Seat caps. If Licensee crosses a Tier threshold or exceeds a Seat cap, it must upgrade within 30 days. Licensor may request reasonable proof of eligibility. For Indie, Licensor will not require annual certifications and may request proof only for cause.
4.7 Headless/Worker Seats. Non-interactive batch/render/simulation use by or for the same Licensee. Node-locked per instance; each running instance requires its own Seat; no concurrency with the same Seat.
5.1 Payment Models.
All fees are exclusive of taxes. Licensee is responsible for VAT or similar taxes other than taxes on Licensor's net income.
5.2 Merchant of Record; Paddle Terms Control. All purchases are processed by Paddle as Merchant of Record. Paddle's Buyer Terms govern the Payments Domain. This Agreement governs all other matters, including license scope, IP, use restrictions, eligibility, support, audits, and remedies. The parties will interpret this Agreement to avoid conflict with Paddle's Buyer Terms within the Payments Domain.
5.3 Payment Failure; Chargebacks; Refunds. If a payment fails, is reversed, or is charged back, Licensor may suspend or revoke the affected licenses immediately. Refunds (if any) are determined by Paddle and may require deactivation. Licenses obtained via fraudulent or reversed transactions may be permanently revoked.
6.1 Ownership of Software and Outputs. All intellectual property in the Software remains with the IP Owners. Licensee retains ownership of Customer Assets and may use, sell, or distribute them, subject to third-party rights, applicable law, and §6.2–§6.5.
6.2 Packaged Assets. Indie/Pro/Studio/Enterprise may create, monetize, and sell Packaged Assets produced using the Software.
6.3 Toolkit Components. Licensee may not sell, license, or distribute Toolkit Components, nor tools that expose or depend on Toolkit Components, except under a separate written agreement with Licensor.
6.4 Intermediate Files. Licensee may not sell or license Intermediate Files as a primary product to third parties. Transient transfer of Intermediate Files to a third-party render vendor is allowed only where the vendor operates solely on Licensee's behalf and does not retain rights or reuse the files.
6.5 Third-Party Rendering. Use with third-party renderers is allowed. Any Intermediate Files remain subject to this Agreement and must not be used to bypass license terms.
6.6 Extensions. Licensee may develop and distribute Extensions that interoperate with the Software, provided they (i) do not include, copy, or expose Toolkit Components; (ii) do not enable use of the Software without a valid license or bypass licensing; (iii) clearly state they are not endorsed by Licensor; and (iv) comply with any published developer guidelines. Licensor may withdraw permission for specific Extensions that materially impair security or licensing.
Licensee shall not: (a) sell, rent, lease, sublicense, lend, or distribute the Software; (b) share or redistribute license keys or activation files; (c) reverse-engineer, decompile, or disassemble the Software except as permitted by law; (d) circumvent license or copy-protection mechanisms; (e) remove or obscure copyright or attribution notices; (f) engage in pooling or sharing that bypasses Seat limits; (g) use the Software in violation of applicable law.
AI/ML restrictions apply — read this section carefully if you plan to use Natsura outputs in any AI/ML context.
8.1 AI Use License Required for Model Training Activities. Without Licensor's prior written agreement (an "AI Use License"), Licensee shall not use the Software, Customer Assets, or Derived Datasets for Model Training Activities or to create, sell, publish, or distribute Derived Datasets.
8.2 Inference & Private QA Allowed. Use of models for inference on Customer Assets is permitted. Private, internal evaluation/QA that does not produce a dataset or model offered to third parties is permitted.
8.3 No Substantially Similar Model (Limited Non-Compete). During the Term and for 24 months thereafter, Licensee shall not use the Software, Customer Assets, or Derived Datasets to develop or train a Substantially Similar Model for commercial distribution to third parties. This §8.3 does not restrict independent development without use of the Software, Customer Assets, or Derived Datasets, nor does it restrict in-house models used solely to deliver Licensee's own services without distribution.
8.4 Relief. Breach causes irreparable harm; Licensor may seek injunctive relief in addition to other remedies.
8.5 Path to Compliance. Licensor may offer standard AI Use License terms (e.g., revenue share or fixed-fee). Contact Licensor for approval prior to any Model Training Activities.
The Software may collect limited pseudonymous technical data (e.g., license status, version, OS, device fingerprint, coarse performance/usage metrics) to enforce licensing and improve functionality. Personal data, if any, is processed according to Licensor's Privacy Notice (link available in-app and on the website) and applicable law (including GDPR). Roles: Licensor is controller; Keygen (licensing) is processor; Paddle is an independent controller for the Payments Domain.
Lawful bases & purposes. Licensing enforcement and fraud prevention (legitimate interests), support and quality (legitimate interests or performance of contract), payments (Paddle's purposes), and compliance (legal obligation).
Choices. Non-essential telemetry can be disabled where provided in settings. Telemetry does not include Customer Assets or content.
Retention & transfers. Technical data is retained for the minimum period necessary. Transfers outside the EEA use appropriate safeguards (e.g., SCCs). A list of sub-processors and the DPA is available on request.
10.1 Certification.
10.2 Audit. With 10 business days' notice (no more than once every 12 months unless for cause), Licensor may conduct a remote audit limited to records reasonably necessary to confirm compliance. Auditors are bound by confidentiality and will minimize business disruption. No on-device intrusive scanning.
10.3 Remedies. If a material variance (≥ 10%) is found, Licensee shall promptly (i) pay shortfalls and (ii) upgrade Tiers/Seats as needed. Licensor may suspend licenses for unremedied material breach after a 30-day cure period.
The Software may include third-party libraries or open-source components under separate licenses, detailed in the "NOTICES" file or documentation. Those licenses govern their respective components.
12.1 Support Levels.
12.2 Updates. Subscription and perpetual licenses include updates as specified in your plan. Licensor is not obliged to provide future updates beyond those terms.
THE SOFTWARE IS PROVIDED "AS IS" AND "AS AVAILABLE." TO THE MAXIMUM EXTENT PERMITTED BY LAW, LICENSOR AND THE IP OWNERS DISCLAIM ALL WARRANTIES, EXPRESS OR IMPLIED, INCLUDING MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND NON-INFRINGEMENT.
TO THE MAXIMUM EXTENT PERMITTED BY LAW, LICENSOR AND THE IP OWNERS SHALL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, OR FOR LOSS OF PROFITS, DATA, OR BUSINESS. TOTAL LIABILITY UNDER THIS AGREEMENT SHALL NOT EXCEED THE AMOUNT PAID FOR THE SOFTWARE IN THE TWELVE (12) MONTHS PRECEDING THE EVENT GIVING RISE TO THE CLAIM. NOTHING IN THIS AGREEMENT EXCLUDES OR LIMITS LIABILITY THAT CANNOT BE EXCLUDED BY LAW (INCLUDING FOR DEATH OR PERSONAL INJURY CAUSED BY NEGLIGENCE, OR FOR FRAUD OR FRAUDULENT MISREPRESENTATION).
This Agreement remains in effect until terminated. Licensor may suspend or terminate immediately for willful misconduct (piracy, fraud, deliberate circumvention, unauthorized redistribution). For other breaches, Licensee will have 30 days to remedy upon notice. Upon termination, Licensee must stop using the Software and delete all copies. Customer Assets created before termination remain Licensee's property. Termination does not affect accrued payment obligations.
15.1 Payment Reversal. Upon chargeback or payment reversal, Licensor may suspend or terminate affected licenses immediately. Refunds, if any, are determined by Paddle.
This Agreement is governed by the laws of France.
Business Customers. Any dispute, controversy, or claim arising out of or relating to this Agreement shall be finally resolved by arbitration under the Rules of Arbitration of the International Chamber of Commerce (ICC). The seat of arbitration shall be Paris, France. The language of arbitration shall be English, and the English version of this Agreement shall be the authoritative text in all proceedings. The United Nations Convention on Contracts for the International Sale of Goods does not apply.
Consumers (EEA/UK). Nothing in this Agreement deprives consumers of mandatory rights. For consumers in the EEA/UK, (i) the arbitration clause does not apply; (ii) you may bring claims in your local courts; and (iii) local consumer law (including any right of withdrawal for digital content where applicable) prevails in case of conflict. A French translation is available upon request.
If arbitration is deemed unenforceable for any party, disputes shall be subject to the exclusive jurisdiction of the courts of Paris, France, except where consumer law provides otherwise.
Licensee may not assign or transfer this Agreement without Licensor's prior written consent, except to a successor in a bona fide merger or acquisition, provided the successor is not a Competitor and agrees in writing to be bound by these terms. Consent will not be unreasonably withheld, conditioned, or delayed. Licensor may assign or delegate its rights and obligations to its affiliates or successors.
18.1 Force Majeure. Neither party is liable for delay or failure to perform due to causes beyond reasonable control (e.g., natural disasters, war, civil unrest, labor disputes, power or Internet failures, government actions).
18.2 Breach. Licensor may terminate for material breach following notice and failure to cure in §15.
18.3 Effect of Termination. As in §15.
18.4 Survival. Sections 1–3, 6–11, 12 (to the extent of accrued obligations), 13–17, 19–23 survive termination.
18.5 Perpetual Viability (No Guaranteed Offline). Perpetual licenses are terminable only for material breach under §18.2/§18.3. Offline activation is not guaranteed. If online activation is permanently discontinued, Licensor will use commercially reasonable efforts to provide a workable path for compliant perpetual licensees of the affected Major Release.
Licensee agrees to comply with all applicable export and sanctions laws and will not use or transfer the Software in violation of such laws.
20.1 Changes. Licensor may modify the Software or this Agreement. Material changes will be announced via the Software, website, or direct email notice. Licensee's continued use after such changes take effect constitutes acceptance. For perpetually licensed versions, new terms apply only to updates Licensee chooses to install.
20.2 Severability; Waiver. If any provision is held unenforceable, the remainder remains effective. Failure to enforce any provision is not a waiver.
20.3 Entire Agreement. This Agreement (including documents referenced herein) is the entire agreement between the parties regarding the Software and supersedes any prior terms or representations. In case of translation discrepancies, the English version prevails (without prejudice to mandatory consumer protections).
20.4 Precedence. This Agreement controls over purchase orders or other documents for the Software. Within the Payments Domain, Paddle's Buyer Terms govern; in all other respects, this Agreement controls.
Licensee is responsible for safeguarding accounts, license keys, activation files, and device access. Prohibited: sharing accounts/keys, embedding keys in public repos or CI artifacts, or exposing activations in public images. Licensee shall promptly notify Licensor of suspected compromise and cooperate in mitigation.
22.1 Benchmarks. Public benchmarking is permitted provided results are truthful, reproducible, disclose versions and hardware, and clearly state whether pre-release builds were used. Pre-release builds require Licensor's written permission for publication.
22.2 Publicity. Licensee may truthfully state that its assets or projects were "made with Natsura." Use of Licensor's names, logos, or trademarks beyond nominative fair use requires written permission and adherence to brand guidelines.
23.1 Licensee Indemnity. Licensee will defend and indemnify Licensor and the IP Owners against third-party claims arising from (i) Customer Assets, (ii) Licensee's breach of this Agreement, or (iii) use of the Software in violation of law.
23.2 Vendor Indemnity (Optional; Enterprise only). If expressly agreed in an Enterprise order form, Licensor will indemnify Licensee for third-party claims alleging that the unmodified Software infringes IP rights, subject to customary exclusions and remedies (e.g., modification, replacement, or refund of depreciated license fees).
