Ah, OK - I do not see anything like that yet - just to be sure, you see this in Rendered display mode, correct, but not in a full render or raytraced vp? What happens if you `UnifyMeshNormals`?

Correct. `UnifyMeshNormals` has no effect.

Hi Robin - please run `SystemInfo` in Rhino and post the results - this is feeling a bit video-card related to me…

Hm, I do not see any of this on Mac either. It does seem like a display thing and not an import thing - can you please save off, with its texture just one of the meshes that shows the problem, make sure the new file still looks incorrect, and send me that?

OK, this is really very strange.

The act of exporting the problem meshes and opening the exported file fixes the problem. It doesn’t just fix it in the exported file, it fixes it in the original too even without having to close and reopen the file.

I’ll try to record it happening.

Edit: here it is in all its glorious weirdness:

I am doubly mystified - does the fix then stick, in the original file, if you close Rhino and then reopen it??

I haven’t tried. But I will.

Also, I’ve got a couple of other glitches on my Mac that apple think are hardware related and I need to take it in to be repaired. Do you think it’s conceivable this is a hardware issue?

The fixed textures stay as long as the original file is saved after the ‘fix’. If it isn’t saved then when reopening, the blue patches reappear.

After saving, it seems to be permanently fixed. I tried:

- Quitting rhino and reopening
- Restarting Mac and reopening
- Quitting and deleting the exported mesh and textures then reopening

All resulting in the main file opening and displaying the textures correctly. At least I now have a work around whilst this is investigated further.
