At all,
Your Welcome.
The likeness of the same demon is because, it is the FPSC demon that huants us all.
If the textures are not right for your shader of choice then make them as you need.
Shaders give me a headache. they are different for each one you like it seems.
This model should work with bond1 viral shaders with texture modification. and the shadow should appear smooth and not blotchie.
I will upload an .obj file later so you can rig it with the biped of your choice for the tail and horn things.
As you animators know that editing a imported biped file is a bear and not even worth modifying, just add your costume stuff to the end.
Have fun
Nothing but coffee in my veins
