Does Rendered and Arctic modes supposed to look the same? I thought arctic is always white.
Is that a pictureframe object that has been modified? If so it has a per object displaymode override.
Also reset display mode settings under Tools > Options > Views > Display Modes
This is an image that is imported with
_hightfield with added picture as material and pixel colors
Arctic and rendered haven’t been touched:
Thanks for reporting! It’s a bug, Arctic should not show the vertex colors. I’ve created a YT item: https://mcneel.myjetbrains.com/youtrack/issue/RH-57467?project=RH
