Multi Resolution will not take visual effect when toggled to sculpt mode.
@Sergey Sharybin (sergey): you are still working on this, right?
So just a known limitation for the (limited) time being with a bright outlook for the forseeable future :) ?
I'm a bit unsure what the problem was, but I'm guessing this is resolved now. Let me know if this is not the case.
Yeah a later update solved it, thanks
