Hello,

I have a question regarding Houdini 16.5
This is what i did:
1. Created “Sphere” object
2. Turned it in to pollygon object
3. Used under “Pyro FX” tool named “Explosion”
4. Now i made some adjustments and went to “Pyro import” node
5. Selected “import_pyrofields” node
6. Selected “Save File” tab and used“Save to Disk”

I am confused a bit about this.
Questions i have regarding this:

1. So it saves cash file to the disc but can i later change the way simulation looks in “Pyro_sim” node (inside there are many nodes but mainly changing: nodes named as: “Resize container”, “Smoke Object” and “Pyro solver”)
And if i change that do i need to save new cash file out or…?

2. If you select “Smoke Object” node (node that is inside “Pyro_sim” node)
there is tabs like “Visualisation, Multi, Density, Temp etc are those ONLY for visalisation in the ”Scene View" ?

1. You need to save new cache files out whenever you change your sim
2. Yes, the visualization is only for the viewport
