Quixel Megascans Goes Free on Fab, With New Terms That Allow AI Training on the Scans

Quixel is making its full Megascans library free on Fab and has updated the terms for all Quixel assets to allow training AI models on Megascans and Megaplants. The library's real-world scans become free to download as Fab listings update, and teams building their own generative tools can use the same scans as training data.

• The full library is free. Quixel says the entire Megascans library is going free on Fab, and GameFromScratch puts the collection at more than 23,000 assets.
• AI training is allowed. The updated terms cover all Quixel assets and specifically permit training AI models on Megascans and Megaplants.
• Recent buyers get refunds. Anyone who bought Megascans or a Quixel Bundle in 2025 or later gets a refund to their Epic Account Balance and keeps both the license and the new AI rights.
• Listings switch over through November 12. Quixel's post on X, as quoted by GameFromScratch, says Fab listings update through November 12, so an asset that still shows a price may not have flipped yet.
• Studio licenses stay on contract. Companies with a Quixel studio license continue under the terms of their existing agreement.

Quixel's updated terms let you train AI models on real-world scans

The licensing change applies to every Quixel asset, and it extends to people who already paid. Quixel says refunded buyers "keep your license and get the new AI rights."

Quixel says the change supports environment generation: "Your AI models can now learn from real-world scans to help you generate varied, photorealistic environments for your projects." Quixel does not specify any model, tool or training method.

GameFromScratch saw no updates to the linked asset license or the Fab EULA and suggested they may change on the same November 12 timeline, so teams planning to assemble training sets from Megascans should confirm the updated terms appear on the Megascans listings on Fab before relying on them.

How refunds work for Megascans and Quixel Bundle purchases made in 2025 or later

Refunds go to your Epic Account Balance. Quixel says that balance can be spent across Epic Games products, not only on Fab.

The steps Quixel lists:

• Log in and accept the terms. Sign into your Epic Account and accept the latest terms if you haven't already.
• Wait for the credit. Refunds will be visible in your Epic Account Balance by the end of 2026.
• Check your balance on Fab. Log into your Epic Account on Fab.com and look in the top right corner.
• Contact support for problems. Quixel directs any issues to Fab support.

The cutoff is the purchase date. Megascans or Quixel Bundle purchases made in 2025 or later qualify; Quixel's post does not mention refunds for earlier purchases.

Megascans has been free on Fab before, and studio contracts stay as they are

On its own site, Quixel describes its catalog as 3D assets captured from the real world for games, film, archviz and more. GameFromScratch reports that Epic made those assets free at Fab's launch and again a few months later when the library migrated from Quixel to Fab, so this round reopens access for anyone who missed those windows.

Studios on a Quixel studio license are handled separately. Quixel says those licenses continue under the terms of each contract and asks studios with questions to contact their representative.
