VrayClipper smudges
Hi
I'm using the VrayClipper quite often without problems, but in this recent scene I get these weird smudges. They are sharp pixelated and they come from geometry that's supposed to be cut off by the VrayClipper. If I set that problematic geometry to invisible, the smudges go away. But these are hundreds of objects (buildings) and some produce smudges, some do not. I need multiple renders from different clipping planes, so setting different buildings from visible to invisible for each render isn't an option. Also, the smudges change if I change the visibility of various objects. They don't just go away from one object. The more objects are visible, the worser it gets. I can't find the reason.
Actually I CAN say that the more geometry there is between the camera and the clipping plane, the worse it gets.
The Vray clipper is a mesh/box that envelops the parts that I want to disappear, hence it's set to "subtraction". I have tried to invert the box, flip the normals and set the operation to "intersection", which results in the same clipping, but also produces the same smudges.
I also shut off GI, used a different camera from another angle - same smudges.
The environment of the scene is a standard daylight. There are no effects (toon, edge etc) on the scene. It's very very basic. The only "odd" thing about the scene is that the problematic buildings are not 3dsmax native, but imported CAD geometry, I hope that's not the reason. The normals are correct, the vertex all welded. There is no smoothing on the faces.
I realize it's hard to find the problem without the scene, but maybe someone has experience with the problem and the solution is right there.
Using 3dsmax 2023, Vray 6.20.02
thx in advance
*edit*
Setting "Max transparency levels" from 50 to 200 solved the problem. Thank you Mark, I really appreciate your help. I know I can always count on you.
No problem Mark, just ask if you have more questions. Happy to help.
