Substrate Performance concerns & Questions

Hey we are starting a new game and see substrate will be on by default soon. (By 5.7)

What is your expectation for using this for games?

Do you use it for Fortnite? If not, is there a plan to use it for Fornite?

Are there any guidelines you would suggest for authoring substrate materials that are performant for a 60+ FPS game?

Will the traditional Material authoring be deprecated in the future?

Hi Weston, let me answer your questions as best as I can:

What is your expectation for using this for games?

We want all games to utilize Substrate as much as possible and have worked very hard to ensure it performs equally, if not better, on all platforms for our 5.7 release.

Do you use it for Fortnite? If not, is there a plan to use it for Fortnite?

We have been using Substrate to build our content, and we plan to enable Substrate by default in a release very soon.

Are there any guidelines you would suggest for authoring substrate materials that are performant for a 60+ FPS game?

I would suggest taking a look at the Substrate guide on the Epic Developer Community we currently have available: https://dev.epicgames.com/documentation/en\-us/unreal\-engine/overview\-of\-substrate\-materials\-in\-unreal\-engine. There is a performance section towards the bottom, which will be updated with more information as we approach the 5.7 release date. Additionally, a talk was given by Nathaniel Morgan at Unreal Fest Stockholm this year, which I recommend you check out once it is released on our YouTube channel. Please keep an eye on it.

Will the traditional Material authoring be deprecated in the future?

Yes, with the production release of Substrate, we will start putting the old material authoring workflow on the deprecation path. However, we have made sure that there are fallback options for developers to make the transition smoother. All of this should be covered in the guide I posted above.

Please let me know if this answers all your questions or if anything remains unclear.

Thanks for the swift reply! I’ll relay this to our team.

I can’t seem to find the Nathaniel Morgan video on the channel, is that not released yet?

EDIT: Nevermind I cant read! Lol

Thanks again
