We use our own software for real-time 3D display (not pre-rendered images).

You can try out the free version of our software to see were the beard will go:

Hello,
Can you confirm which maps can be used? (diffuse, specular, glossy, bump, displacement...)
Also can you confirm the max definition of maps (2k, 4k allowed?)

Only diffuse. The idea is to get the realism mainly from the texture image.
2K or 4K maps allowed.
