Is there a way to add custom repellents to the white water solver? for example if I want to add in more repellents in a specific area, is there a way to do it?

Coding can be very helpful, however the fx lead I have ever had cannot code at all. If you have a good eye and can figure out clever ways to do something,there is usually nodes for whatever you are trying to accomplish. In my personal experience I have found too many FX TDs get to wrapped into their coding that they can lose track of the big picture, or end up wasting a lot of time coding something that there is already a node that does the same thing.
For anything that doesn't have sop node, there is always VOPs.

I am working on a project with several different sources. I would like to be able to have control over specific parameters for separate sources. For example in a pyro simulation I would like to be able to have a different gas released for each fuel source. Is this doable without having to use several different pyro solvers.
Any help would be greatly appreciated,
Cheers.

You can get particles to not travel in straight lines by adding a gravity force. you can also use a pop force and add turbulence to get a curling type a effect. Another option is a curl noise node.

I believe that they have replaced attribute bias with relax iterations. It doesn't do exactly the same as attribute bias, but it gets close.

Micropolygon rendering is a good way to get quick renders. Where as Physically based rendering will give you a much more detail, but will have a slower render time.
With getting rid of your blockiness, lowering your division size is pretty much the only way to get rid of it. You can change your Division Method from Div size, to Max Axis and set it to 500 - 800.
If you can't handle the high resolution required to get a perfectly smooth sim, get your sim as high as you can. Then put down a volume blur, this will blur the voxels together, it will reduce some of the smaller detail, but it will get rid of the blockiness.
You can also try turning on motion blur.

On the pyro node itself, you need to enable “Add Rest Field” under the “Initail Data” tab. Once that is done then the dual rest field will work as well.

VDB from particle fluid is a node that creates a VDB volume from particles or points. It is commonly used to surface a flip simulation. VDB particle fluid doesn't itself create a fog volume, but you can use a VDB convert after and convert it from an SDF to fog volume.

If you are looking to just model cool or crazy things, Houdini may not be as good a place to start as a program like Zbrush. However, it is a really solid all around software (animation, dynamics, rendering, modelling), but it is geared very heavily towards the effects side of the industry. If you could tell me a bit more about what it is exactly you are looking to do, and how much time you wish to dedicate to it then I could probably give you a better idea of where to start.
In the meantime if you want to learn houdini you can start with the lessons from sidefx.

Other good places would be FXPHD and CMIVFX, but they are not free lessons.

I am trying to find the replacement for the “state” node from popnet, in the new dops. Specifically I am looking for a way to set the pops initially as stuck.
