As some of you already found out, it is quite possible to set up differential growth not only on a line but also on a mesh. This tutorial goes into the details of doing exactly that while allowing for some degree of art-directability (is that even a word?) of the growth patterns.
Also some of you mentioned that you despise the diving in and out of a solver when tweaking parameters. To alleviate that process we’ll also go over how to link values so that you can tweak parameters while working on a level outside of a solver.
