Hello everyone,

My name is Sébastien Hillaire and I am the co-author of Substrate along with Charles de Rousiers.

Substrate Materials have been released as experimental in Unreal 5.1. As described in the documentation: “Substrate is a new way of authoring materials that replaces the fixed suite of shading models, such as Default Lit and ClearCoat, with a more expressive and modular framework that provides a greater range of surface appearances and a wider parameter space from which to work. Performance for Substrate Materials scales according to complexity and desired budget of a project, with legacy materials having a similar cost as before.”

For 5.1, the Substrate docs will be hosted on the Dev Community. They can be found here. Please be sure to read all of the docs before posting, especially the Experimental Status Section to learn more about current limitations. We will likely update the docs over time based on your questions and feedback. Furthermore, a sample project with training and usage examples will be released soon.

We are starting this thread for general feedback and discussion. If you have more focused feedback that might require a longer conversation, please start a new thread under Rendering and apply the Substrate tag. Before replying to this thread or starting a new topic, please search the forum first to see if there is already a relevant thread.

We and other Epic employees will try our best to answer as much as we can, but cannot promise responses to all of your posts. We do read everything here and will try to incorporate your feedback into future work.

NOTE: Substrate is the new name. The previous, now deprecated name, was Strata.
