Hi - For some reason when I block geometry in Rhino 8 (rendered display) shadows are not cast. When I explode the block shadows are cast (and prior to blocking). Here are images of the underlying geometry (casting shadows) and what I get when I turn the geometry into a block. The blocks are set to cast and receive shadows, so this must be a different issue. Any ideas?
Thanks,
Matt Winkelstein
Hi Matt, I think this has been fixed - what sr are you using? Can you copy/paste the output from the SystemInfo command in Rhino?
-Pascal
Sure - here it is:

dude its that 8 gigabytes on your gpu try using a i9 quad core with a Samsung p1000.
Hi Matt -
I’m not seeing that in a quick test here:
A few things to try:
Rendered mode is a modification of the default mode. What happens when you use the default settings?-wim
Would you be able to clarify that, what should I have for this setup? It’s a company machine that came that way. Would love to be able to describe the preferred specs.
Thanks!
I was getting that issue with all display modes and on laptop screen alone. I did notice that depending on the level of zoom, shadows changed, disappeared and reappeared depending on the camera based clipping shadow radius setting. And a radius setting that got the shadows to work with one model would need to be changed for a different model. In all cases the default settings required adjustment of clipping radius to activate and refine shadows. Not clear to me why each different model and level of zoom would require a shadow setting adjustment. Ideally getting good shadows wouldn’t be this challenging… Is it possible this is due to inadequate graphics card video memory (8 GB)? These are not highly complex or heavy models.
Thanks
Hi Matt -
A lot depends on the extents of the scene and extents of some of the objects in that scene. If you can post or upload (Rhino - Upload to Support) a 3dm model, the developer can take a look at what’s going on here.
