Hello, I am studying muscle system, and prepared a setup with a cycle inplace walk animation for my creature. That way, everyhting worked fine. Next step i tried switching the old animation with a new one, running in space, much faster than before. The result now appears completely broken, seems like muscles cannot follow the bones promptly, they're remaining behind the bones and intersecting each other they are not able to deintersect. I just tried to: • increase the stiffness for muscle-to-bones and muscle-to-muscle constraints, in Properties Sop • remove all damping values, in Properties Sop • increase substep, in Solver • increase constraint iterations, in Solver • added velocity stiffness factor (fresh new property in 19.5.409), in Properties Sop • added velocity blend, in Properties Sop • enabled velocity blending, in Solver • increased velocity damping, in Solver None of them worked or gave acceptable results. Any tips on how can i fix it? Thanks Update: speeding the solver x2 faster seems to give better results, although still not perfect. Not sure this is the right path anyway.

Hi, what would be the best approach to create this type of simulation (machine gun smoke simulation)? Any Ideas, scene file strategies would be very helpful! Video file: M1A1 Abrams Firing From Hull-Down Positions_1.mp4 Here 's a gif preview -

Link to tutoial -> https://gum.co/imSYS In this comprehensive stand alone tutorial we will go over how to set up scene-scale clustered pyro simulations and blend them together post-simulation to make it appear as if it is one large simulation. This process will lower simulation time, allow for higher resolutions, and be more efficient when saving to disk because there are fewer voxels. This process will also optimize large scale pyro scenes, so that simulations are only calculated where absolutely necessary and blend them together so that it appears as if it is the same volume. This tutorial comes with all digital assets, a documented and fully set up file as well as a starter file for following the tutorials along the same as I work through them. An intermediate tutorial for those looking to speed up their pyro workflow, learn some VEX and create massive sims. Includes a documented scene file and all digital assets! Hope to see everyone leveraging these optimizations in the future to create massive simulations and squeeze in those extra few iterations before deadlines!

Hey! Question about fast moving pyro sources. I included a scene which is similar to my actual scene. I have an object from which I want fire to emit. However, when the object starts to move quickly, the flames practically die until the source comes to a stop again. This seems realistic, like if you move a match really quickly. However, that is not what I want to happen. I still want fire even when the source is moving quickly. What can I do to fix this? Emit more fuel when the source is moving quickly? Should I link velocity to the scale of the fuel source? Is there a better way? Also, turning on fuel advection helps slightly. Any help would be appreciated. Thanks fastpyro.hipnc

In this tutorial we will go over how to set up optimized pyro clustering with oriented DOP containers in Houdini given a piece of geometry moving through a scene. This process will lower simulation time and be more efficient when saving to disk because there are fewer voxels. Link to Tutorial -> https://gum.co/TqUNR We first go over how to get things set up quick and easy and in the second half of the tutorial we make further optimizations using VEX. We'll look at how to rewrite cluster points to do exactly what we need it to, which includes rewriting the resample sop using VEX. An intermediate tutorial for those looking to speed up their pyro workflow and learn some VEX. Includes the scene file! Hope to see everyone leveraging these optimizations in the future and squeezing in those extra few iterations before deadline! You can reach me at trzankofx@gmail.com for questions or comments.

Hey Guys , i have a fast moving flip source , and cant get smooth shape , it look like emitter shape while emitting , i tried many different solutions like , putting time blend sop,trail sop , increasing substeps but always get same result . i had this problem in realflow too , but i fixed that by incearesing min substeps , but it didnt work in houdini , is there any solution for fixing this problem in houdini ? thanks

Hey all! Long-time lurker, first-time poster. I've learned so much from OdForce. Thank you all for everything you've done! I'm having a bit of an issue with fast-moving smoke simulation I'm trying to do. I've tried upping the substeps in addition to having the source geomerty strretch along it's path of animation. The particles emitting seem to work alright but the volume just isn't showing up. If you leave the noise-field on, you'll see that it's definitely emitting, but when you turn it off you won't see any smoke. Any ideas? I've attached the file. Thanks so much! plasma_Smoke_trail_004.hipnc
