Hi Tyger_purr

I agree.  I feel that given everything that is available in the material room,   it is time to rethink mesh design,  and as crocodilian pointed out texture map size.   The above head is an experiment using diffuse+specular+displacement.  The largest texture map used is 2000x1000.  The poly count for the head is 20k.

Cheers
