Vrayclipper - strange behavior

[davision]

VrayClipper -- a great feature, is acting strangely in this one instance.

I wanted to create an object that was broken into two pieces but started out appearing intact. The idea was to create two copies of the object and have a dedicated vrayclipper for each object... one clipper would be flipped 180 degrees from the other one.

As a test I created the attached scene.

I realized that having two vrayclipper objects in the same plane causes problems (even if the vrayclippers are set to only include their respective object). You'll see the sphere on the right has no top surface (is hollow). If I move the vrayclipper on the left (which includes only the left sphere in its effect) upward or downward, then the right sphere will be capped. But when the clippers are coplanar there is a problem.

If I overlap the two spheres entirely, it gets even weirder. See attached images and max file.

I've talked to the developers and there is no solution for your setup with the current implementation of the VRayClipper. Sorry

And if you offset it vertically by a very small amount? Other than that would adding slice and cap modifiers work? It might for simpler geometry.

[davision]

Yeah, slice and cap will probably suffice. I like how clipper can create irregular cuts (when used with geometry) so I prefer to use it when I can.

Peter,

I understand there might not be a solution right now, but isn't it a bug and not just a limitation? Especially since the clippers are only set to Include their respective sphere. Clearly, the clipper on the left is affecting the sphere on the right.

For the first case try with Mesh clippers (there should be a fix for the plane clipper someday). I meant the overlapping spheres scenario that is not going to be fixed.
