Api: questions about the 3d materials

[marquesinijatinha]

Would it be possible to provide some info on how to render the web api 3d materials/textures?
1) How are the dye colors and textures merged? Is there some blend mode applied to them?
2) what do 4 values arrays in the material_properties parameters (in the dye info) mean?
3) how do the flags in the renderMeshes parts affect the rendering of the model/texture?

1. The GDC talks say they are based on Photoshop blend modes to make it easier for artists to build and debug assets. I obviously don't know have the actual code they use but I've written some functions based on stuff I found online. (see "Blend Functions" https://github.com/lowlines/three-tgx-loader/blob/master/src/three.tgxmaterial.js)
2. This is likely just a product of how it gets stored in binary for performance. I only know what the albedo ones are for (PBR).
3. Please can an expert from Bungie answer this question! I'd like to know this as well! 👀
