I created a catsuit out of a character. I exported the necessary body parts, re-imported the OBJ, added a skeleton in the setup room, removed the bones that were no longer needed and gave it a texture, finally. Then, I loaded the original figure and conformed the catsuit to it. The result is, that the legs move into the wrong places. (IK is turned off for everything.) These positions seem in some way to be the default for the character, because if I ALT-click on the dials then they take this position, too. But why?

If this worked it would be a very easy way to produce a catsuit to any character, even a cat ;-)

Zero the catsuit (via the Joint Editor). Memorize figure (Edit menu --> Memorize --> Figure) Resave to the library.

Thank you, Little Dragon. Seems like this worked.

And by the way, this is the shader for the catsuit.

So how do you eliminate the poke throughs? I suppose I could hide the poking through body parts But I was hoping to use this as a mesh catsuit, but with all the poke throughe that wouldn't seem to work.

It's not pokethrough as much as it is that the catsuit you made from the V3 body is probably the exact same size as the body itself. You'll probably have to scale it (maybe 101-102%), and then reposition it around the body.

In Poser 5 I'd use a displacement map. Now, here's a thought. Instead of a mesh pattern as a transmap, use it to control the model surface and forget about the catsuit object. That is, feed it into the displacement map input to get the physical thickness, and also use it to control a blender node, which combines the body texture with the material for the mesh suit. You could do the body texturemap as a pre-built texture, using layers in the paint program, but you'd still need the distinct displacementmap texture.

Displacement seems to have done the trick. I figured the problem was the catsuit almost the exact size as the character, but i had already tried Deecey's suggestion about scaling the catsuit up and I was just getting poke throughs in other places.
