Black Spots on Cyberfaces

Good Evening everybody, i've been experimenting some things on CF's and come across a glitch with black spots on the cyberfaces face & arms. Is there a way to remove it?

save it as DXT5 not DXT1

I see, is it okay to import it by DXT5 even though in 3DM Tool the original textures says DXT1?

save teh face files as dxt5 with interpoled alpha, and the arm as dxt1 without alpha, problem solved
