Hello
I'm wondering if it's possible to inspect volume attributes in the stage context?
I created a volume in the obj context.
I imported it inside the stage using a scene import node.
I want to check the min and max range of the density attribute.
I tried to select a node then go to geometry spreadsheet > primitive mode, but it's all empty.
Thanks and see you soon,
GS

Hey Grendizer you have to use the "Scene graph details" window. Look for "primvar" values.
However, what's the best way to use several primvar values in a MTLX material library network node? For example I want to get the min and max density, min and max flame, min and max temperature, etc...

I would calculate the min/max in SOPs

Thanks a lot for this great solution!
I didn't know about spare inputs [www.particle-effects.com]!
