Should be able to. Do you have “show vertex colors” in Viewer Settings turned off, by any chance?
No, it’s on. I appear to be cursed for some reason
I HAVE FIXED THE ISSUE!! turns out combine OBJ vertex colours was enabled in settings which made things not work
Maybe that’s a sign that it’s time for me to clean up the Settings menu, I think that one was added for a really old version before I added code to load materials separately…
