Thanks BB! I won't be able to test this until much later tonight - but it looks like you found the answer to the problem of no shadow on the leg (and elsewhere).

Yes, this is an outdoor scene with no walls or structures in front of, or on either side of  V4. I'll check the light settings, as I recall it isn't white, but a very light gray? I used a light set that came with the structure, and made modifications from there - but didn't change the colors.

I think I need to check the shaders for the building as well, they might be using a displacement map that is reducing (difusing) the intensity of the IDL?
