asegura 0 Posted April 6, 2019 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. Share this post Link to post Share on other sites

Midasssilver 13 Posted September 26, 2019 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. Share this post Link to post Share on other sites
silkey 4 Posted December 4, 2019 Hiya, my 2 Cents. I'm using a custom meshing setup with vdb's and my flickering was due to culling in the fluid compress. I turned off Cull Bandwidth to solve it. Share this post Link to post Share on other sites
