http://www.cracked.com/blog/the-6-most-ominous-trends-in-video-games/ This is a good read, makes you stop and think for a moment where are we headed in this indrusty.
6 different diffuse textures with 6 of it's specs and 6 normals 18 textures total for the entire material? But there isn't an error in the material editor. Should that be ok? It's like a component can only have 3-4 textures painted per square anymore than that will crash.
https://projects.blender.org/blender/blender/pulls/107827 I too remember this branch, and having downloaded it. As mentioned here: https://blenderartists.org/t/where-to-get-blender-3-6-or-4-0-alpha-with-mesh-to-sdf-volume-nodes/1527446/9 Where someone links to a branch you can compile, if you're up for it.
