I've got some basic CSG objects that screw up badly with OpenGL in Moray. 
Lutz, you want to have a look at them?  They're intersections between
spheres and prisms.

I've also run into a difficulty.  When you add a udo object to a CSG object,
it can no longer be evaulated, which is really bad in the OpenGL mode if
you've used a lot of intersection and differences, since the shape of the
real object is totally hidden.  Any way this could be done?

(And yeah, it's no longer a beta, but might as well get my plug in now ;) )

Well, I guess so<g>.

UDOs have no polygon information, so it's impossible to calculate CSG
shapes.....
