whodini Posted May 5, 2014 Share Posted May 5, 2014 Hey guys, I'm able to get instancing to work with an animated source after I studied a hip file posted on this forum on the topic. However I cant seem to get instancing to work on source that isn't animated. Here's what I want to do. I have a source that is not moving and it's constantly pumping smoke in to the scene. I want to have multiple containers (via instancing) that have about 20% overlap and have them automatically resize when density inside them. I've attacheda hip file, and you will see the smoke only gets to about 2 container instances and cuts away the density as if those two clusters were the only ones its in. cluster_test.hip Quote Link to comment Share on other sites More sharing options...
Skybar Posted May 5, 2014 Share Posted May 5, 2014 you will see the smoke only gets to about 2 container instances and cuts away the density as if those two clusters were the only ones its in. And that is true. Your source is only inside the first 2 containers and emits smoke inside those. There is no emitting at all in the other containers. What you want is for the smoke to be able to pass from one container to another, and that is quite another setup. Take a look at the "CombinedSmoke" example file which does this.

whodini Posted May 5, 2014 Author Share Posted May 5, 2014 (edited) thank you skybar! I I havent been able to locate that combined smoke example though Edited May 5, 2014 by rhussain Quote Link to comment Share on other sites More sharing options...
Skybar Posted May 5, 2014 Share Posted May 5, 2014 Inside houdini, go up to the Help menu -> Example Files. Then search for "combinedsmoke". It should show up then. Quote Link to comment Share on other sites More sharing options...
whodini Posted May 5, 2014 Author Share Posted May 5, 2014 wow you're right, thats bizarre, I actually searched for that in the houdini help directly after hitting F1 to pull up the help and it wasnt there. Nevertheless thisi s great! Quote Link to comment Share on other sites More sharing options...
Hello world Posted May 8, 2014 Share Posted May 8, 2014 @rhussain are you talking about the pyro clustering? if thats the one you are talking about,it is good but it got some limitations.smoke from one part of cluster may not move to another and i guess you have to emit fire or smoke from points Quote Link to comment Share on other sites More sharing options...
whodini Posted May 9, 2014 Author Share Posted May 9, 2014 yea.. unfortunately this wont work for what I'm doing. Clustering / Instancing is better suited for contrails, or streams of solid smoke from a missle or something along those lines. I'm working on a sim that has one source that is static and constantly pumping smoke and vel into the grid. Quote Link to comment Share on other sites More sharing options...
