Vray Clipper Refraction Problem

[Mokiki]

I am currently running into a problem when using the vray clipper.

What I am trying to do is use objects to cut into a mesh and then use a copy of the cutter objects with a refractive material to basically fill the holes.

So my current workflow is:

1. Scatter objects with forest back onto the object.
2. Clone
3. Convert Clone to Editable Poly
4. Pick the freshly converted clone as clipper object
5. Add Push Modifier to the Forest Object, so the polys don't lie directly on top of each other.
6. Add Refractive Material (in this example Glass Material)
7. Render

The inside of the refractive object will render Black as if it doesn't let any light through. (Affect Shadows is ticked)

If I don't use the clipper and just shove render the refractive objects intersecting with the mesh they'll render as I'd expect.

I am using 3ds Max 2019 and Vray Next 4.03.02.28334

you probably need to expand the clipper to be just above the surface of the mesh the drops are sitting on.

Sorry Dmitry I am not really following.

The clipper is in mesh mode and uses a clone of the refractive drops, which sit on top of the surface.

Hello,

Does it help if you increase the Max depth parameter in the refraction options of the glass material ?

Best regards,

The Max depth parameter has no effect. I tried going up until 60 or so which should be way more than needed and there was no change.

Then it would be best if you could send a scene for some more investigation.
