Hello, I think this is a ray-tracing or shadowing issue, and I'd like to find out how to turn it off. I have a bunch of spheres on a lattice, and when you turn the lattice a certain way - for example with a lattice corner out of the plane of the screen, "staring at you" - *some* spheres get "blackened" (with one-sided light source) or become sort of transparent (with two-sided light source)... I'd like to turn off this feature and just view the spheres as fully "solid" volumes rather than transparent or projected objects, regardless of lattice orientation...
Any help is appreciated! Denis
