  1. Hi there! I'm still new to houdini and I'm having a lot of trouble on a project and was wondering if I could have some help or at least some direction on how I could achieve this effect. The project is to simulate a pool of lipstick with a rotating animated object in the center. To resemble the lipstick viscosity I wanted to make a very dense fluid/particle sim, with some clumps of even denser material. Here's the best reference I could find for the effect https://youtu.be/zBGgfPXwLMQ?t=165 . I tried to make a Flip sim with high viscosity and create a viscosity map with a noise sop for those extra viscous chunks, but I couldn't make clumps like I wanted to. I don't even know if the Flip solver is the best tool for the job, but I couldn't think of anything that would get me closer to what I wanted. I also tried to create a few pieces of RBD objects in the middle of the pool, but it didn't work at all. I just really have no idea if I'm on the right direction. I'll add the hip file aswell as a flipbook of the meshed sim. I am using 18.5 by the way. Any help or direction is appreciated. Thank you! lipsticktest.mp4 LipstickPool.hiplc
  2. Hi! I'm actually trying to get trough the tutorial series of Houdini "Destruction FX", and I need to use the Minimal OpenCl Solve for a Pyro Sim. But as soon as I turn it on, my console pops up with tons of errors showing up! I couldn't find something talking abt it on the internet as it is a pretty new feature, so if anyone knows how I could solve that it would be perfect.

  3. Hey all, I have a whole solaris setup and ready to render, I'm trying to do a slicker multi-shot workflow but I cant seem to get render frame ranges per shot. On the render settings node you cant specify the range, only on the very end USD_ROP node can you specify this. I've tried injecting metadata using 'storeparametervalues' for the start/end frame but I cant seem to use that information down in the USD_ROP (blue). Currently I'm using a switch to switch between my two shots here (orange). I'm relatively new to Houdini so I may just be missing something obvious but in the USD_ROP frame range I've tried: $shotStartFrame /HoudiniLayerInfo.shotEndFrame (this happens when you drag the value from the scene graph) Any help at this stage would be amazing. Thanks all
  4. Houdini won't run

    I cant start houdini apprentice - licence server shows that everything is ok, but after starting app a see only splash screen and nothing after that. No messages, no crashlogs, it just closing. I make clean install of last version of houdini, but nothing changes. Since last time when i runs houdini i don't made any system changes and other stuff, just regular work. I use windows 10, and i don't know what happens with this software, and a need help.
