PBR textures should have no lighting information (With the exception of Ambient Occlusion). This is unlike the old system where Ambient Occlusion would be put into the diffuse map.
you could..but that defeats the fun of it. It honor system based, but since there's no prize or anything only the people who actually play along seem to stick around.
Thanks. Thats right, I'm actually using a particle system for that right now, I should switch to a screen effect, that would be much easier to control.
Such a perfect resource. Thank you. The Ninja Theory one looks really interesting, looking forward to learning more about the system they used for the face capture.
