Hello everyone,

I'm in the midst of creating a cream/milk pour shot. Current WIP can be seen here:

I'm performing the sim & meshing in Houdini, then exporting via Alembic to C4D for rendering with Vray.

The primary portion that I'm trying to create is the thin film of milk fat / cream that would appear on the side of the bowl (similar to a wet map) during the pour. I had tried an approach that solely used attributes, but I don't think that would give the exact look that we're after, as that thin layer of fat has a very unique feel & appearance that I don't think could be appropriately recreated simply by reshading the side of the bowl wet-map style.

At the moment, I have a thin layer of points that I'm trying to convert to a thin fluid mesh for that purpose, but the mesh that I'm generating has an enormous amount of aliasing - almost like crop circles.

I've tried Volume smoothing, VDB smoothing, VDB Dialate/Erode, a VOP point look-up smooth/blur (which almost works, but the surface erodes too much - I really need the mesh edges to be precise), and can't really seem to nail it.

Below are some links to one frame of the points + a scene file; any thoughts on how to remedy this?

Thanks!

Pavel did a great demo of this using ‘thin sheets’

Thanks for the link! That sounds like a great tool to experiment with. I guess right now though I'm focusing a bit more on simply smoothing the particles I already have.
