Shadow Problem with Block Objects

Rhino Rhino for Windows
1

Hello,

I’ve noticed a glitch with block objects. They become see through when viewing in the viewport rendered mode with shadows enabled. It seems to happen when the objects are far from the world/viewport origin. The same objects don’t do this when at the origin! And non-block type objects seems ok.

Thank you,

Can you run SystemInfo in Rhino and post the results?

Hi Pascal, is that the one far from the origin?
I’ll post the info when I’m back.
Thanks

Got it now. thanks - I see the other one - not really very far from the origin though. I’ll see what I can find out.
Looks like it is the skylight shadows only, so far, that does this.
As far as I can tell this works as expected in the V8 WIP…
