Quest won't display SBSAR materials

I'm using UE4 and Substance materials, when I apply the SBSAR material to my scene it displays properly but once I side load the project to the quest all I see is a flat grey material.  Does the Quest support this type of material and if so are there any specific Project Settings or options I need to enable to get it to work?

    Hi Maxer!

    When using Unreal, the editor is using by default Shader Model 5. The Quest runs on Android, and that doesn't support Shader Model 5. You need to switch to ES3.1.

    Substance Materials (when just downloaded) are not supported, because the shader neetwork is to complex. But you still can use generated texture maps. I guess if you stay within solid PBR-Shaders, you shouldn't have any issues. Besides the fact, that all Shader Model 5 materials will be compiled to ES3.1

    I am running more tests by myself and I am also very interested in using Unreal and developing specifically for the Quest. I am gong to publish more documentation and tests on my blog: https://fattybull.com/oculus-quest/

    Hope that helps a bit,
    cheers!
