In POP-Fluid, where can I apply noise to the viscosity?

Recommended Posts

Hello;

In Houdini 16.5, I would like to add "viscosity" to a "Particle Fluid" simulation using a noise pattern, so in DOP I add a "POP-VOP" node (and AANoise in it ... ) after "Source Volume" which doesn't work.

Where could I apply noise to the viscosity?

 

Thanks for helping.

bypass the fit and you got noisey viscosity....

looks like your fit is pushing visc values into positive ++

I think I should use the "fit" because "Anti-Aliased Noise" creates an output from -0.5 to 0.5 and I also need the viscosity from 1 to 500.

i think by the scale of your generated geometry, with such high values multiplying a low frequency noise pattern you're not gonna see a lot of variation. Bind your visc out to Cd to visualise your noise pattern in dops.
