Every time I add a new primitive object it gets auto-generated UV map. Which means that if I switch to sculpting and turn on dynamic topology, I get a warning that dyntopo will destroy UV data and vertex colors and whatever. EVERY. TIME. There is no way to turn that off. There is no way to send that warning to the console log, where it belongs. There is no way to turn off auto-UV. You have to uncheck it every, goddamn, time.
Which genius in the devteam thought this is a good idea?
Um, no, it was added.
In 2.79 objects are not auto-unwrapped.
In 2.79 the dyntopo warning appears, but also purges the UV/vertex color data (as it should), so the next time you turn dyntopo on, the is no warning.
