"This is because you can't export Maya shaders to Unity. "
While it is true Unity has it's own shaders, according to the new Unity 2018.2.15f1 this is no longer an issue with the import textures/materials feature it does it for you.
Besides the issue for this person and myself, thus my post, is that Maya is not exporting the supporting embedded files in the FBM folder. Not that Unity doesn't support materials from outside apps.
Here is what I know and have done thus far to get this resolved on my end:
1 mesh is good
2 texture file paths are green checked according to FilePathEditor
3 Using Blinn not Arnold for materials/textures
4 checked Embed Media in Game Exporter plugin.
5 no FMB folder is created no matter what I do.
6 I've read that all the info is just embeded in to the FBX and when if you click the file it creates the FBM folder, but that isn't happening either. I also check the file in FBX Review and it shows no textures.
7 I tried Lambert, named my files all correctly, have read countless posts about this issue with no constant answer and have just updated to 2018.4 sp.
It creates an FBX but no FBM folder is exported thus no textures. The issue for me is this not how Unity handles textures in an FBX which now it does support via the extract textures/materials tab
Please help!
