Hey there, I've encountered imo strange behaviour with my flip Sim. I got Liquid running down stairs. The Liquid should be a bit viscous so I introduced the attribute on SOP Level. For the collider I used volume collisions and a pretty high-res (.002 voxel soze on a 5m Stair) VDB to which I am pointing in my Static Object. When I simulated the liquid with f.e. 100000 viscosity (I tried values from low to super high) its just behaving like water. As soon as I decrease the resolution of my collider it works as expected, or If I increase the resolution of my Flip Sim while leaving the high-res collider as it is it also works as expected. My Question would be: Is there a dependecy between the resolution of the collider and the fluid? does a low res fluid not work properly with a high-res collider? I thought the more resolution on my collider (not too much to keep it efficient) the better. But it seems like that is causing issues -- in my case the solver ignoring the viscosity and the fluid splashing like water while showing correct viscosity values in the GEO Spreadsheet... Thanks in advance and stay safe!

Hey folks, simple question... is it possible to use the POP Spin or POP Torque (DOP Nodes) on a Vellum Grains sim. I am emitting Vellum Grains continuously and after the sim i use the Grains to copy f.e. Boxes onto the Points. But i can't get the Geo to rotate. They stay static at one axis and don't rotate. So my question is: Is it possible to use POP Spin or Torque on Vellum Grains? Cheers

Okay lol i had to think about an hour or so, then i posted. BUT, i got the Solution! For everyone who runs into the same problem -> if($FF>1&& $FF<48, ($FF%8==1),0)

Hey Guys, i got a question. I got a vellum sim and i am emitting every 8th Frame one sphere into my sim. I did it with -> $FF % 8 == 1 but now i want that emission just between Frame 1 - Frame 48. So between F1 and F48 i want every 8th Frame an emission. How can i get this with an expression? Cheers and Thanks!

Yeah i tried these Methods and retime did the job. But i tried to do this by an attribute or something that i can run f.e. a noise over my flip particles and link that to the attribute that stops the motion. This way i could achieve that the freezing begins at the under section and stops at the top. But Thank you!

Hey Guys, Imagine an object which fills with liquid over time. When the object is full of liquid i want the motion of the Flip Fluid stop oder decrease over time. For example: - Object fills with Flip Fluid from Frame 1 to Frame 96. - Liquid and all motion of it slows down from Frame 96 to Frame 144, at Frame 144 everything is not moving anymore. I tried some pop wrangle inside my DOP but i cant get this working. Any suggestions? Should i do this after the DOP in SOP Level in a Vop/Wrangle or could I achive this inside my DOP? And How? Thanks and Greets, me

Convert Mesh to fluid that stays the same size

Yes, I made a simpler Setup and now it worked. Thanks! -
Hi everyone, i got a question and can't figure a way out. Imagine a bottle, and a mesh that perfectly fits into that bottle. I want to convert the mesh into a flip fluid and when i turn on gravity i want it to be as big as before. So my bottle is filled. The reason why i want that, is that I have a drop coming from above and falling into that bottle. When it collides with the fluid inside the bottle, I want a little splash and then the sim is done. How can i get a filled bottle that stays filled after I turn on the Sim. Maybe someone got the same problem or a solution, but i can't get my head around it! Thanks and Cheers!

Hi everyone, I got an issue with rendering a Lot of Spheres in Octane. I scattered 1 million points on a surface and copied Spheres on it (with the CopyStamp SOP). I packed it but it does not render and crash. Can somebody tell me how i can render Instances in Octane or point out some Informations, i can't figure out how to do it right due im new to Houdini and Octane. Cheers!
