Hi, I'm trying to understand the "gas particle to field" node in dops, with the ultimate goal of creating something similar to this:
https://vimeo.com/244246258 [vimeo.com]
In the comments, he says, "I am emitting a blast of particle on 1 frame, and add their velocity to my smoke with the Gas Particle to field.".
So I though, cool, I'll start with transferring color and then move to transferring velocity (once I have a handle on Cd). Problem is, I can't even get the color to transfer properly.
I checked out the example file in the help docs for gasparticletofield node...but it not using a sim, so a bit confusing. I also, checked out @mestela file on CGwiki, but still stuck.
If anyone can give me some pointers, that would be great.
.hip attached for reference
Thanks

Hi,
That's because you don't have a Cd volume. So you have to create that first in SOPs or DOPs, and use that field to color the smoke field using Volume Visualization SOP for example:

cncverkstadOh! Nice, cncverkstad. Thanks for that! Just showing off now.
I was actually trying to figure out the shock wave parts. It looks like he shot particles towards the center of the scene, then after a few frames...maybe shot particles outwards from center...twice (then transferred the v of the particles onto the pyro)?
The ripple through the smoke is really throwing me off.
Thanks again for the scene file!
