Does anyone know how to apply a .btx file to the Multires modifier? The manual says how to save it (click Save External obviously), but nothing about loading it. All I could find anywhere was this, but when I load the .btx nothing is applied at all.
I’m actually using 2.79… I’ve been repeatedly following the steps in the StackExchange article to a tee with no effect, so I started preparing my own step-by-step to prove that it doesn’t work, and then it actually worked.
So apparently I have to write down the steps every time to get it to load. I expect this isn’t over yet… I’ll report back if I find what the issue was.
Ok I think I’ve worked it out already. You have to get out of Sculpt mode into Object mode before saving the .btx, otherwise it just saves its unmodified state.
