scale might make a difference, i haven't tested it , but it could screw up the normalization, try setting everything to scale of 1.

I cant really help unless you tell me what errors you are getting.

Nadester: i have no idea what's happening there.. it looks like your normalmap is wierd. Are you sure you have colormap set as entSkin1 and normalmap (with specular map in alpha) as mtlSkin1? Are the textures from a WAD or a tga in a folder? If they are in a WAD they probably wont work.
