Vray Clipper mesh not filling

[Macker]

Hi all,

Back again with another VRay Clipper question.

I've got a project where I've been using the clipper to cut a section through a building, and it's been doing a great job of it, filling in even open/clipped geometry where necessary.

On a particular shot I've had to use a mesh to clip away parts of the building, and it doesn't appear to be filling in the geometry as the standard clipper does. Is this by design, or am I doing something wrong?



Thanks,
Chris

I am sure the Chaos folks will have some good input, but first thing I would try it to triangulate the cutter geometry.

Is the grass FP geometry? What happens if you exclude it from the VRayClipper?

Also, is the geometry consisting of closed volumes? For VRayClipper to work properly volumes must be closed. Geometry imported from CAD software is not always closed, hence my question.

Hi Aleksandar,

Yes most of the volumes of the building that are clipped are closed volumes.

Like I said, these are filled when the default clipper is used - it's only when I use mesh mode that it doesn't fill them.

Thankfully the client preferred the straight section so it's not so much of an issue now - but would still be good to know why it wasn't filling.

Best send the scene to determine the exact cause. Simplify it as much as you can.
