As the title says, I'm having an issue swapping out materials on a project where certain mesh objects are not being updated until I reopen the file.
Does this happen in the viewport? Or only on Neon renderings?
Only in Brazil, Neon is correct.
Is Edge softening involved? I've just seen this problem on another model - the symptoms are exactly the same as yours. I actually thought this bug had been fixed - but obviously not.
