Hi @Rob23
It’s close to impossible to give you any advice based on just a screen grab. First things to do is a) run SystemInfo command in Rhino and post the result here and b) post your 3DM file either here on Discourse or upload it via this link, if the file is either large or you don’t want it to be public - reference this topic for Support to find.

That said, my guess would be either an outdated graphics driver or that you are really far from world origin (0,0,0).

as Jakob said, please post your systeminfo and your file if possible.

Hi Rob -

Please stay up-to-date!
The current version for Rhino 8 is 8.32, released two weeks ago.

A question to answer as well: rendering with V-Ray or Rhino Render?

Legacy Rhino render

I don’t think Legacy Rhino Render has had much attention at all, so I wouldn’t be surprised if it doesn’t work well if at all.
