This is a collection of 45 heads both male and female with black, asian, coloured and caucasian and races. There are textures included as well. There is also 3 levels of detail for each head (low- med- HiPoly).
I recommend downloading the OBJ.rar which is importable by most 3D programs and the TEXTURES.rar to get the textures. ELSE Download the .rar of the format you want and also download the textures.rar to get the textures.
