[BUG] Reporting a Clipping Plane Rendering Bug in Rhino7

Description

When using a Clipping Plane, I have noticed some Reytraced aesthetics rendering bugs in the viewport.

Hi Alan -

Is this file-specific on your system? If so, we’d need the file.
In any case we’ll also need the SystemInfo.

I have also seen this in various cases; not too difficult to reproduce: cycles-clipping-plane-artifacts.3dm (2.0 MB)

Hej -

I’m not sure that there aren’t different issues that are being reported in this thread.

The issue that is visible in the file that JD posted has been fixed, and is possibly related to or the same as your other thread -

As Nathan noted in that other thread, the issue is fixed in Rhino 8 and it’s not possible to back-port this into Rhino 7.

If you are seeing an issue in Rhino 8 with external blocks, please start a new thread and provide the 3dm files that are necessary to reproduce that issue.
Thanks,
-wim

@wim If the solution from 8 can’t be “backported” to 7 I would suggest to allow time to fix the issue in a different way in 7, since McNeel will leave a group of loyal customers behind on 7 SR 3X because of the decision to NOT support macOS except for the most recent versions. ClippingPlanes has not worked in Rhino 7 if you rely on Rhino’s render Engine (Cycles). NB Chaos has solved ClippingPlanes in V-Ray 6.

Hi -

We are now focused on fixing issues in Rhino 8 before turning to new features in Rhino 9.
Thanks,
-wim
