it would seem that glow maps do not work and causes crash if the 'skin tint' option is enabled - but without it, the skin will just be very dark brown, but the glow map is working. i save the glowmap texture as BC 5 compressed dds (my test is a 1024 map), and the material has glowmap filepath, glowmap checked, Emmitance enabled & with a bright color, and Skin Tint disabled it does not crash and there is a working glowmap on the skin, but like i said, no skin tone mixing
