Rhino 7 for Mac, texture only showing when object is selected

I have a simple surface on which I have mapped a PBR texture. When the surface is selected, the texture shows correctly in rendered view. When I deselect the object, the texture is removed and the surface appears white. The same file works as expected in Rhino 7 for Windows.

I’ll upload the file separately as it’s quite large.

Hi,

The issue is resolved by changing the Perspective view to a Perspective projection again instead of Parallel or by disabling the Ambient Occlusion texture map in the PBR. The issue is not exclusive to Mac and I see the same on Windows in this case. I’m filing this as a confidential bug report with your file as RH-62493 thanks.

Thanks for looking into this. My apologies for forgetting that I’d changed the viewport to parallel on the Mac.
