Geoff,

It seems like a Z buffer related problem :

If you draw an opaque polygon _after_ you draw a transparent one, and the Z
buffer test is on, than the Z buffer test will be performed before the blending
occures. This means that if the opaque polygon is farther than the transparent
one, it will be obscured. The solution for that is to draw all transparent
geometry last. Performer should take care of that, unless requested otherwise.

Hope that helps

Ran
