Licensing
Last updated: 16 August 2026
These terms govern products purchased directly from penumbraworks.com. Products obtained through Fab, the Unity Asset Store, Gumroad, ArtStation or any other marketplace are licensed under that marketplace's own end user licence agreement, not these terms
1. What you receive
On payment, we grant you a non-exclusive, worldwide, perpetual, non-transferable licence to use the product under the terms below. You are buying a licence to use the product. You are not buying the product itself, and ownership of all intellectual property remains with Penumbra Works.
2. Licence model
Each product is licensed under one of the models described below. The model that applies is stated on the product page and on your invoice. Unless stated otherwise, products are licensed under the revenue tier model in section 2.1.
2.1 Revenue tiers
Products are licensed under three tiers based on the licensee's revenue. All tiers grant the same rights; only the price differs.
| Tier | Applies to |
|---|---|
| Indie | Under €100,000 gross revenue in the preceding 12 months |
| Studio | €100,000 to €5,000,000 |
| Enterprise | Above €5,000,000 |
How revenue is calculated. Gross revenue from all commercial activity during the 12 months before purchase, across the licensee entity and any parent, subsidiary or affiliated entities under common control. Thresholds are stated in euro. Revenue is not limited to income from the project the product is used in.
Your tier is fixed at the time of purchase. If your revenue grows past a threshold afterwards, you do not need to upgrade or pay a difference. The licence you bought remains valid.
A licence is held by one entity. Within that entity, any number of individuals working on its projects may use the product. It may not be shared across separate legal entities. A parent company's licence does not cover a subsidiary, and vice versa.
Enterprise licences are arranged directly. Contact us at support@penumbraworks.com to discuss terms. Enterprise agreements may vary from these terms; where they conflict, the signed agreement governs.
Declaration. You select your tier at checkout and are responsible for selecting accurately. We may request written confirmation of tier eligibility. Where a product has been used under a tier below the correct one, we may require payment of the difference.
3. What you may do
- Use the product in an unlimited number of commercial and non-commercial projects
- Modify, adapt and build upon it for use within your projects
- Distribute it as an integrated part of a finished product, such as a game, film, application, or rendered image or video
- Use it in client work, provided the end client's use stays within these terms
- Use it in projects with unlimited revenue
- Show and promote your own work containing the product freely. Screenshots, trailers, devlogs, streams and store pages are all fine.
4. What you may not do
- Redistribute, resell, sublicense, lend or give away the product files, in whole or in part, in a form that allows extraction or reuse
- Include the product in an asset pack, template, marketplace listing or any product whose primary value is the assets or tooling themselves
- Share your licence key or download links
- Use our product images, renders, trailers or other marketing material to promote your own project or product
- Sell or distribute renders, stills or image files of the product, whether or not modified
- Distribute the product on a platform where other users can extract, download or reuse it independently of your project, including user-generated-content platforms. Contact us if you need this, as it can often be arranged.
- Use the product, or any part of it, as training data for machine learning or generative AI systems
- Use it in NFTs, blockchain assets, or any product where the asset itself is the traded item
- Remove or alter copyright notices in source files
- Claim authorship of the product
5. Source code and tooling
Where a product includes source code, you may modify it for internal use and ship compiled or built output. You may not distribute the source in a form that lets a third party reuse it independently of your project.
3D asset products ship as game-ready files. Working scenes and source files are not included by default. If you need them, contact us and we will quote separately.
6. Team and client work
You may share the product with contractors working on your project, provided they use it solely for that project and delete their copies on completion. You remain responsible for their compliance.
When delivering to a client, the product may remain integrated in the delivered work. Handing the client the raw product files requires them to hold their own licence.
7. Updates, engine compatibility and support
Updates. Updates within a product's current major version are provided at no additional cost to existing licence holders.
New major versions. Where a new major version is released, existing licence holders are offered a substantial discount. For upgrading email sales@penumbraworks.com sending the order number and proof of purchase, we will be happy to assist you!
Engine compatibility. Each product lists the engine and software versions it was built and tested against. We fix defects in our own work. Where an update to a third-party engine or application breaks compatibility, we assess it case by case and will tell you clearly whether a fix is planned. Either way, we would rather know, so please report it.
Support. The product current support status is displayed in the support section of that single product store page. User support is provided by email at support@penumbraworks.com.
Discontinuation. We may discontinue a product. If we do, your licence continues unaffected, and we will make the final release available for download to existing licence holders for at least 12 months from the discontinuation date.
8. Payment and refunds
Purchases are processed by Lemon Squeezy as Merchant of Record. Lemon Squeezy is the seller of record, handles payment and VAT, and issues your invoice.
Refunds are covered by our Refund Policy.
9. Termination
This licence terminates automatically if you breach it. On termination you must stop using the product and delete all copies. Work already shipped in compliance with these terms before termination may remain in distribution.
10. Warranty and liability
Products are provided as-is. We do not warrant that they will be error-free, or that they will meet your specific requirements or work in every environment or engine version.
To the maximum extent permitted by law, our total liability for any claim relating to a product is limited to the amount you paid for it. We are not liable for indirect or consequential losses, including lost profits, lost data, or project delays.
11. Changes
We may update these terms for future purchases. The terms in force at the time of your purchase continue to govern that purchase.
12. Governing law
These terms are governed by the laws of the Republic of Lithuania. Where you purchase as a consumer, you retain the protection of mandatory provisions of the law of your country of residence, and may bring proceedings in your local courts.
