Hi. I'm very new to Houdini and trying to create Brain Coral procedurally (See image reference). Does anyone have a link to some tutorials on this that are up to date for Houdini 14?

Thanks in advance for your help.

PS. I've been tying to follow the tutorial “Working with Noise
Published Sept 24, 2013 for Houdini 12.5 ” but the VOP SOP does not seem to work in H14 the way it does in H12.

This is no ordinary noise, you have to look at Scott-Grey reaction diffusion to generate procedurally that pattern

good luck

How do you use this VOP? If downloaded it but I don't understand it.
Can you maybe share hip file?

I don't know if this will help. But here are some coral/growth tutorials you can check out. These really helped me when I was attempting to build coral sims.
