Double surface on meshing

[asegura 0]

Hi there,

I'm experiencing this super annoying problem when flattening surface using particle fluid surface in Houdni17.

Problem is a random double surface (top and bottom) when I only want top one. I'm working on a character splashes and everything its working just fine except that I can't find a reason why these random frames are showing double surfacing. In my setup, because characters run long distance I decided to use animated tank tracking the character position and regenerating particles per frame, then I meshing using flatten geometry surface option and "Use Bounding Box" checked with correct bbox values and centroid. I'm also using narrow band in my sim. Any help? this is kind of frustrating since it makes no sense at all.

Hi there,

I’m having a similar issue. Did you end up solving it? 

Cheers!

Try changing the rebuild sdf parameter to NONE on the particle fluid surface node. You can also try to turn on limit refinement, and leave it at zero. Second, turn off rebuild sdf.
