Where do I find the attributes available for the fire rendering at Cycles (flame, color, density...). Where is the list? or at least, how do I find which ones are available? They are not listed in the custom variables (says it's blender's programming api? are they hidden?).

Everybody talks about them but I'm not able to find them, even on the official guide at blender.org. In fact, the help pages are outdated and contain nothing about the fire and smoke and fire modes for smoke dynamics and the parameters.

This question is, in fact, a general question: Where do I find the attributes available?.

For reference: http://www.blender.org/manual/physics/smoke/flow_object.html There you can see it is always referencing a particle system. But in the volumes you have the smoke and fire AND fire options. Why doesn't it talk about it?

I'm using blender 2.74

  • $\begingroup$ Nope, Chebhou. I saw it already. But gandalf3 says it. But i don't want him to tell me. I want an official guide or at least a place I can see the attributes available. My question talks about it. I want to know why, and where. $\endgroup$

  • $\begingroup$ I understand, there should be something official ( i had a link to old doc but it keeps redirecting to the new empty one ) it is for getattribute() $\endgroup$

  • $\begingroup$ There must be official documentation about this. There are some parameters i just don't understand. For example, flame Rate in flows. $\endgroup$

  • $\begingroup$ @darkgaze AFAIK there isn't, at least beyond the few out of date mentions on the wiki and manual. The flame rate is a simulation setting, and has nothing to do with rendering/cycles..? $\endgroup$

You can find that Attributes on the official Page for the Attribute Node: Attribute Node - Blender Manual

Or on the Stack Exchange Thread: All Possible Attributes - Stack Exchange
