So, I made this thing, people started calling it SPACECAT, it's a material validation sphere to help artists create accurate and effective materials in PBR pipelines, it comes with source art for testing bake settings, and an ID mask for material segregation. If you’re a student, SPACECAT is free to you, just email me at jjeverson@gmail.com and I’ll get you sorted, if you can't swing the 6.50 for it, also shoot me an email, it's up on Cubebrush http://cbr.sh/729fc
Also If you guys want to see a quick tutorial on how to setup and do some quick bakes in Substance Painter let me know in the comments, Cheers!
