I am bit confused with h12, in H11 used to be a source apply node, which by way is till in docs but not in DOPs, with a Multiply Attribute parameter. I was using it to control the emitting amount of h smoke, reduce it or sop it. How can I do this in H12?

All of this is now done with the fluid source sop and source volume dop.

I know but I but I count find this parameter or something that will help me control the amount of emission, I am going to have a look again. Thanks

In the source volume DOP, there is a parameter called “scale source volume”, it can be key framed

exactly, the “scale source volume” parameter controls the scale of the volume to be added to a specific field in your simulation. Same goes for temperature and velocity. Next to the scale you can specify how volumes are added by choosing one of the source volume merge options (add, multiply, max etc).

The multiply attribute parameter is not necessary
