Hello, all!
I’ve been toying a bit with the (awsome) IMM-tool, but I’ve kinda run into a snag. I can’t seem to find a way to control the twist of a curve properly. There’s the little green indicator at the end which shows the twist of the curve, and when I mouse over it it shows a little rotation thingy, but when I try to click it I just pick up the end of the curve instead. I’m guessing there’s a hotkey or a trick to it or something, but I haven’t been able to find it.
try holding shift key
For me that only smooths the mesh. 
I would love to do this as well - I’m in the middle of making straps for a soldier and adjusting the curves starts twisting the strap into his body.
