Masking Volume Noise?


Recommended Posts

hey folks.

I've been following this amazing tutorial by Tim J but wanted to learn how to add attribute paint or another noise to use as a mask so only certain areas are effected by the volumetric noise

I'm quite new to Houdini and have no idea!

thanks in advance.

You can multiply your noise by a volume mask like so. Mind that if your noise goes *through* the geometry your mask would sit on the surface, so transfer your mask to points that fill the geometry (like with Points from Volume SOP).
