VrayClipper not closing cavity

[bobweb]

Hello,

I have simplified the problem to the following: I have two boxes, one with 3x3x3 segments, the middle polygon extruded inwards and moved a little to the side. The second box just surrounds the first box completely. I create a Vray clipper object and let it cut through the middle of the hole. Result: The hole is not completely filled (see images), seemingly as much as I moved the extruded polygon. When I don't move it and everything stays straight, it works.

Is this a bug? I have used Vray 3.40.02 in 3ds Max 2016.

Thanks,
Bob

To make it a little less abstract, here is the use case that led me there: For a medical animation I need to clip away parts of gums and bone to reveal a tooth root. The gums alone work fine and sit at the tooth surface embedding the root, but together with the bone the inner part is vanished. I know this can be done now with two renderings, masks and post - I would just prefer not to have this extra amount of render time and work. I have also tried to use two separate clippers for bone and gums, but that makes things worse, then all holes stay open.

Hello,

Thank you for the simplified scene and the real world example I'll check what is going on and write back as soon as possible.

Hello,

Just to be sure - in the simplified case you need the result to be:



and if you shell the outer box and get



is not good?

Hello,

sorry for the late reply, I was out of office...
The result should rather be, that the hole in the blue box would be completely filled with the outer orange box instead of leaving a hole in the corner. Or to be more specific in the actual case: The gums need to be still visible between bone and tooth (see attached image, which is two renderings masked, combined etc.). The marked area in red is what is missing in the single rendering.



Thanks,
Bob
