What would be the best way to create Material that’s “mostly” the same as a SimpleMaterial or StandardMaterial, but supports a texture that’s sampled a 2D Texture Array? In other words, I’m trying to do something like this , but have the material support lighting and fog and the usual standard mater…

Since 5.0 you can use material plugins to extend existing standard / PBR materials.

Thanks, it looks like material plugins could solve this. But after a lot of hacking, I can’t seem to get the 2D array texture data bound into the shader. None of the docs or samples use textures, and there don’t appear to be any insertion points in the shaders related to samplers, so it’s kind of a…

Thanks Evgeni, I see what you did there… The follow-up question is then, how to attach an array of texture indices to the mesh, so that different meshes can share this same texture, and each mesh render can get drawn with different textures from out of the sampler. (My use case here is using a text…

Yes, to me it’s the right way to do it. If you want specific data for each mesh then attributes is the way to go. There was a number of mistakes in your latest PG that makes it fail for me, here’s a fixed one: Babylon.js Playground Babylon.js playground is a live editor for Babylon.j…

Ah weird - declaring the attributes and varying properties in the UBO section worked for me on mac, but not on PC. Yikes. Anyway thanks for your help!
