Exporting Pyro sim to Maya?? June 6, 2021, 11:02 a.m.

Thanks a lot Deviner! As this file is more technical than my knowledge I have some questions :

So here's what I understand from your scene:
- box1 : You start by a cube
- vdbfrompolygons1 : You convert it into a density fog VDB
- copy_for_3_fields : You duplicate it so now you have 3 densities
- name_to_Cd : You convert each densities into color information
- volumewrangle_your_stuff_here: you create a colored ramps and you apply it into the Color (Cd). To distribute the color, you use the vertical size of the original box.

Now as you can guess I want to use the heat instead of the vertical size of the box. From my Pyro_Import node, I could extract only the heat using a delete node. But my first question would be: how can I know the range of the heat? Does it go from 0 to 1, like the Cd color?

Cheers
David

Thanks. Another question, how can I export the heat and Cd fields in the final filecache node?
BerkErdag said : in the "convert VDB" node, write @name=density for Group.
Should I write in : @name=density @name=heat @name=Cd ?

So I did more tests with this scene and I deleted my isoOffset node and replaced it with a "Convert VDB" node.

Check the attached pic : in the "pyro_import" node, I did a file cache from the import_pyrofields and plugged it into a volume visualisation node, in which I have a gradient. Then I plug this in a convert VDB node and in the bottom of my network, I use another filecache node in which I pout the vdb extension.

I understand the volume visualization node is for the viewport only, but is there a way to get these colors exported to the VDB files? And then how can I recover these colors in Maya?
Thanks
