Grasshopper & Rhino Rendered Display Bug

Grasshopper

Hello everyone,

the latest service release introduced a display bug in the Grasshopper - Rhino rendering pipeline.
Rhino 7 SR5 2021-4-10 (Rhino 7, 7.5.21100.03001

Grasshopper objects with custom preview settings render correctly in shaded, but not in rendered mode. It seems, that one material is assigned to all objects no matter their individual settings.

Shaded:

Is there a way to revert to a previous Rhino version? I’m on quite a tight deadline and this bug is not helping to submit the project :slight_smile:

Thanks @dale.
Any chance to get an installer of previous versions before the bug was introduced?

@mrhe,

It looks like this broke back in Feb.

To get back the old behavior, please run the command “TestCRMMeshDraw”… you’ll have to run that every time you start Rhino until we can get this fixed… The current goal is to get this into 7.6.

Thanks,
-Jeff

I have downgraded to 7.4.21078.01001 and it works again.

Appreciate your prompt response, guys!
