Christian Johansson Posted August 27, 2018 Share Posted August 27, 2018 Hey All, I have a flip fluid sim of a glass filling with liquid, and where the mesh has some bumps here and there when exported, causing some flickering in the render. Someone suggested using a VDB Smooth node in the flip to even things out, but I am not sure where I would hook that up in the network. See the little bumps in the liquid surface in the attached image. If anyone could give pointers or alt solutions I would be more than happy. Cheers, Christian Quote Link to comment Share on other sites More sharing options...
Atom Posted August 27, 2018 Share Posted August 27, 2018 Those bumps may be the result of your collision resolution. Try increasing the resolution of the collision object. To avoid re-simming, you could drop down a VDB smooth or a polygon smooth after surfacing. Quote Link to comment Share on other sites More sharing options...
Christian Johansson Posted August 27, 2018 Author Share Posted August 27, 2018 Hey Thanks Atom, Subdivided the collision object and re-simming. If I need to put the VDB smooth down, where would that go exactly? After the particle fluid surface node? Cheers, Christian Quote Link to comment Share on other sites More sharing options...
Jesper Rahlff Posted August 28, 2018 Share Posted August 28, 2018 yeah you would use the VDB smooth after the particle fluid surface node. Double check that your particle fluid surface node is indeed outputting a VDB. Cannot remember if that is what it is doing by default Quote Link to comment Share on other sites More sharing options...
