Drive pscale by smoke temperature?

[Neo222]

Hey guys,

I'm looking to use the smoke temperature to drive my pscale attribute, however I can't seem figure out how to actually access the temperature attribute to use it elsewhere.

I'm still quite new to Houdini so there is a good chance I'm missing something very straight forward. Any help would be greatly appreciated.

Thanks in advance

volumesampleVOP does that, You can get the closest volume value with this node

Hi~ You can do that with 'fit' function. create 'create attribute node' and typing fit function in the value ( base is 0)

Thanks for the quick reply guys.

Martin I had a quick poke around in the volumeVOP (couldn't find a volumesampleVOP). I did this under the import_smoke Dop I/O node and I couldnt see an input referring to temperature. Am I doing this in the correct place? Is there any chance you can elaborate a bit more on the process of setting this up, as I am not overly confident of the process?

Thanks again

After few hours digging around I managed to get the temperature attribute from my smoke onto my points using an attribute from volume node which i could then reference into the pscale attribute. It seems to be working fine, so I thought I'd post up my solution in case anyone else is having trouble with a similar issue.

Thanks
