Into animation? Here's a #toptip from the studio via our Art Lead Seán Forsyth - this one's for Zbrush fans.

1. Make sure your object is a Dynamesh object

2. Hold down Ctrl and draw your mask stroke on the model (this doesn't work for strokes starting off the model)

3.When your stroke is completed, keep Ctrl pressed down and then hold down Shift
4.Release both Ctrl and Shift together

Voilá - local subdivision in that area, nice and quick!
