just wondering if we have any mental ray experts here, the other day i had to render about 200 thousand spheres, each with a complex shader motion blur and self shadowing. Mental ray just about managed it, after a lot of tweaking, but it was falling over a lot. Its a very ineffiecent method to actually instance all that geometry so I have been looking into using geometry shader to swap in a sphere at render time. I'm very early on in experimentation. but I cant get the geometry shader to react to anything but the default light, i'm assuming i have to link them somehow,.
anyone know how?
