So firstly I just want to express my frustration... I could not use the 3D function on my Apple iMac 2012 because I was having the same issue. Thought maybe the graphics card was outdated but yet here I am with a brand new 2021 Apple iMac with the M1 Chip and having the SAME DAMN ISSSUE!!!!
Whenever I open a 3D template file and I need to edit it, (it's a 3D layer based template) I get a black screen and even if I try work with the black screen and then save the edits, nothing wants to render, sometimes magically it will render for a few seconds, as soon as I flip away from the tab, it goes nuts and shows nothing again. I use these exact templates all the time on a windows pc that is seriously low spec and I don't encounter the same issues.
