how to hide pyro sim source volume? July 27, 2019, 7:15 a.m.

Hey EmamFX
yeah sometimes you might need to hide the source as it might appear very dense and visually look bad. in that case you can use VDBcombine SOP and subtract the source volume from your simed volume, but prepare your source volume before subtracting to have a nice fall off other wise you might end up having a harsh edge.

Thank you very much this makes sense but i'm not getting any result using the vdbcombine SOP and i have no idea why
sorry again i'm still a beginner, and here's the hip file with the vdbcombine SOP

how to hide pyro sim source volume? July 27, 2019, 7:06 a.m.

No hip file attached! Also, that source is where fuel comes from, so it needs to be visible, because that's the hottest part of what is emitting. If you cut the source after a certain number of frames, then the source will disappear. What I'm trying to say is, it sounds like you are assuming something is a problem that is behaving the way it should be.
sorry for that attachment mistake, I added the hip file now if you check it you can see that i'm going for some kind of jet engine effect on the the ground so i only want the result of the sim not the source of it and i don't want to turn off the source, just hide it in the render

how to hide pyro sim source volume? July 23, 2019, 8:50 a.m.

Hello everyone,

excuse me I'm pretty new to Houdini and this may be a really beginner question
but I'm doing a pyro sim (using 16.5) and i'm sourcing it from fluid source with point stamp (calculated velocities on points)
now everything is working good but i want to hide the source from the final result of the sim, it's sourced using a source volume node inside the DOP network but i don't want it to show up after solving as the points now look like a grainy blob in the middle of my sim

I hope this was clear enough, and I attached the hip file anyway
