Sepu

cheating?? how so?

use point deform instead

If you are interested in motion graphics and you are coming from C4D or Maya (Mash) I highly recommend MOPs is a free open source project from Henry (great guy but do not tell him that) for more complex stuff I would also recommend MOP + but first get the hang of MOPs - below is a link on how to get started and use them. or Rohan as well

Now you can load Vdb and instancing them with Bifrost Graph if you are using Arnold.

Is working fine here I can see through. I do not have the red fluid that you have but it should work, the only thing that I noticed is that you didn't have a redshift material applied to the red fluid geo. RS Version 3.0.44

Depending on what version of RS are you using, you might have to enable this guy on the system tab. If that doesn't work, the best thing is sharing a .hip file.

What render engine is this?

set up the active attrib in sops to 0 then just update what needs to be active=1 inside the sop solver. When you are inside the sop solver that is running each timestep so you are overriding the active attrib. hold_active_att.hip

a few thing you need to do to render -Make sure you have the lights contributing to the volume -Be sure that you have a volume shader connected to an output -Make sure that you are using the correct channels from the pyro output -Play with the advanced tab and remap your values if you need to -If you are using the pyropostprocess delete the shop_material (however I can remember if that was introduced in 18 or 18.5) That should do it theoracally Other than that upload a .hip would be easier to see what is happening.

drop an AOV node or use the AOV from the ROP then you choose the aovs that you want or use the custom to grab stuff from RSusercolordata, make sure that the names match in the rop and customaov

Make sure you are using a fog vdb instead.

What do you mean by activating? do you want to use falloff to drive forces or constraints? Depending on what you want you need to use the falloff in pts or primitives. Here is a simple example of animating the falloff to drive a force. falloffDrivingForce.hip

That's just a limitation of RS, you gotta use the area size inside the light properties. Another option is to create your own python state for it.
