Problems with Rasterize Attributes SOP and 'v' values

OK Hi everyone. I'm a beginner who just started learning Houdini through the old version of Applied Houdini. Let me jump right into the question.

In the old version, there was a SOP called “fluidsource” which I find was very cool since it can create a volume while storing some vector data in it's own vector field.

However, after Houdini v17 the SOP disappeared, thus we should now create a volume with the help of Pyro source SOP(which I guess is a SOP that stores by messing around with particles), and the Volume Rasterize Attributes SOP.

The main problem is that if I try to include a ‘v’ attribute to the Volume Rasterize Attribute SOP, it sure does store the value by creating a ‘v’ field, but it also RASTERIZES IT!! I don't want this to happen. I just want vector values to be in the field where there are supposed to be, not to be shown as density values. Since density values are scalar, it surely causes a lot of problems when vector attributes are transformed into scalar attributes.

So the main question is, how can I create a volume that visualizes density values and stores vector values, not a volume that visualizes both density and vector values?

I'd like to get any help if possible. Thx

if you don't want to see the v field then plug in a visualise sop after the rasterise sop and hide v*

and vectors are 3 floats(scalars) so don't be afraid.

to hide certain volumes you can use Primitive SOP/Volumes/Adjust Visualization/Invisible
