just tryed textureing this i got the skin on but sadly it only changes the color of the blp i used (i used old blps from other models) like if i used a red wing skin then the wings would turn red but no detail
then skin i used:
and the result (hard to tell but thats realy dark gray)
so aparently you would need to have a custom blp made instead of reuseing old wings hope someone could do that
say la vi - such is life...
