A powerful procedural tool for quickly generating and animating fungus growth in Blender 3.5 and onward. Draw curves to designate a growth path and watch it engulf any object you put in its way. There are a variety of easily useable parameters to achieve the look you want, and it's built with geometry nodes so if you want to go deeper you can tweak the system for your needs. Also includes a slime mold inspired procedural material.
