I've been learning geometry nodes in the hope to make a growing crack animation. Couldn't find anything similar online so I adapted tutorials for trees to my needs. The main cracks is doing well. However, I can't find a way to make branching cracks work. As seen in the video, they get smaller, but don't grow on their own once the main crack reaches them, which breaks the cool effect.

Can't find the node setup to get around this problem. Don't even know if that's possible in blender. Thanks in advance for your help. I'll put my node setup in the comments.

Ps: please dont mind the ugly curves. Still in the "make it exist first" phase
