Hi all! I recently made a free public post on my Patreon, a bit of a New Year's gift. In my destruction classes & SideFX conference presentations I've mentioned that I often use geometry grouping to define the clustered sections in my RBD sims. However, it takes a bit of work to create the feedback for-each loops to set that up, so I've finally wrapped it up into a helpful HDA. Demo HIP file included as well. (I also included the HDA in the November 2020 'quick tip' post, but this version fixes a bug in the size-based prioritization, so for patrons that have that version I highly recommend downloading this one instead!) https://www.patreon.com/posts/45769153 https://vimeo.com/496659441 Hope you find this useful, and that you enjoy the new year! :-) ~ Keith

Hi people, i have an urgent problem to solve and i have searched everywhere couldnt find anything about the problem i have, so: i have an "rocket launcher" setup, simple circle as an emitter going up i did a cluster setup, and simulations starts without problem, but in some moment when the circle emitter is, lets say 3 cluster container, for some reason pyro wont source the fuel from the object, and that 3rd cluster container just dissapear??? But when the circle emitter gets to the 4th cluster it starts to emit normally??? Im not sure if im doing something wrong or what, but help would be appreciated p.s. rocket starts to go up >220frame rocket.rar

Hello Everyone, I am wondering can some one explain the details of a clustered simulation. I was wondering when I saw the clustering simulation why the individual clusters can't be saved as a scene and have it run on multiple computers since it would work on a renderfarm. So I'm wondering how the actual process works does the simulation have to work simultaneously where each cluster is still somehow referring to each other for calculations.

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!

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.

Hi I have a question about clustering. The problem is. If I cluster on SOPs then when I come to DOPs I get clustered pieces, but the collision guide shows tetrahedrolized geo over the whole cluster piece. Here is a picture When the geometry is this Is there any ways to calculate the collision geo for every piece (which is exactly that piece, because voronoy gives already tetrahedrolized pieces) and then connect them as clusters to get collision geo exactly like the original geometry? Thanks
