Hello,

I would like to have te example file of the flame.

I found this link in the manual for the "Attribute Node": https://blender.stackexchange.com/questions/14262#14267 Is that the full list for the density attribute?

Also what can we type in the temperature attribute?

These things shall be in the manual.

The flame is from the main example file of the course. If you mean the simulated explosion, I added a link to the file in the video description. https://jangafx.com/software/embergen/download/free-vdb-animations/

What you can type in the attribute fields depends on the volume data/vertex data that the object is providing. For the temperature simply use Temperature, it does say this in the manual for the attribute node https://docs.blender.org/manual/en/latest/render/shader_nodes/input/attribute.html

But this is not what the general course is about.
