Fixed it! I think it was an accidental cache mismatch - which I think should still work tbh. Sorted now.

Ugly crosses in pyro sim Feb. 8, 2018, 3:07 a.m.

Had this with sims at work and even had some of our senior FX guys trying to get to the bottom of it. Never got a definitive answer but felt almost like a combo of substep plus an influence scale creating some artefact that busts up vectors in your vel field. You know It's even present in sidefx default shelf sim if remove the visualisation tweaks and look closely.

I recall some success with alternative advection methods in advanced pyro settings and some tweaks in shading on vel tweaks. Can look tomorrow again if I get a chance what helped clean it up

Hey Guys,

Just playing around with H16 ocean tool updates… and am stumped with the ocean foam SOP.

My understanding it's a 2d particle sim that drives my foam shading and should be incorporated in any displacement
- however when rendering with a matching spectrum for displacement - My foam barely renders at all.

I've disabled whitecap cusp shading and you can clearly see the foam renders fine on an undisplaced surface, and does does not work on displacement.

Hip attached.
