Is it possible to change the smoke colour attribute in Cycles, without having to clear the cache and rebake?

  • $\begingroup$ If color is set in the smoke material, it should work changing it from there (so without connecting Attribute node with value Color rather than using color palette right there). $\endgroup$ – Mr Zak Dec 6 '15 at 20:37
  • $\begingroup$ @MrZak That only helps if all your smoke is the same color. Perhaps you could change the colors of the color attribute with nodes though $\endgroup$ – gandalf3 Dec 6 '15 at 21:13
  • $\begingroup$ Yeah, I'd like to have a few different smoke colors missing. Maybe editing the smoke cache file directly? $\endgroup$ – ajwood Dec 6 '15 at 21:32
  • $\begingroup$ Oops: I meant mixing* $\endgroup$ – ajwood Dec 6 '15 at 22:40
  • $\begingroup$ The color attribute comes in via a node, so maybe there is a way to manipulate it then? $\endgroup$ – VRM Dec 6 '15 at 23:41

This does not appear to be possible.

Hopefully in future the smoke system will output a mix factor for the smoke instead of a color, as then the colors of the smoke would be fully editable. Currently the output is the actual RGB color so this is not possible.
