Rendered View Does Not Show Color - Only White

I have a small project where I have multiple layers, each with color for shared view, and material set for when I want to view in rendered. The problem I am running into is that the rendered view stopped working and now does not display color - everything is white! The strange part is that if I close and re-open Rhino it works SOMETIMES!

Bashing my head on this one!

Hi Victor -
There is not all that much to go on in your report, except, perhaps, the “SOMETIMES” part.
That makes it sound like an issue with your machine.
Please run the Rhino SystemInfo command and copy-paste that information here.

The other interesting thing is that if I add a new object and apply a material it works(renders) on some layers and some don’t(is just white).

I’ve attached the file I am working with at the moment.

Hello- here’s what I see in the rendered vp -

Your Radeon driver is getting a little old - you might try getting the latest, from the AMD website and see if that improves things.

When it shows white, do the materials themselves have the correct bitmaps as textures? Can you edit them?


Yeah, what you are seeing is what I used to see/expected to see. I did verify driver for GPU is up to date - latest as of 11/11/22 but that did not make a difference.

Also, yes, the materials have the correct bitmaps, and I can edit them. In fact, here’s what I am seeing:

Notice that the 3D rectangle is on Layer06 with “Grassy” as the material but yet it still shows as white… I’m thinking that something is corrupted but I am not sure why - seems like a bug.

By the way, I can replicate this on new objects as well, so it doesn’t seem to be object related.

@pascal - Ready for some more weirdness? I found a way to reproduce behavior! The color on materials do not show up(all white) if I open the file from File Explorer. If I open the drawing from the “recents” tab when Rhino first starts, the colors show!

Same file - no changes done. It’s simply the way I am opening the file. This seems like a Rhino bug to me.

Hi Victor, thanks, I’ll check this.
Hm, works in either case here. Is the file on the local machine - like on the desktop - or a network, or Dropbox/Google Drive sort of thing?
