I was following the camp fire tutorial on the blender guru YT channel, and i've run into a problem when I try to render my scene. In the tutorial, it says to switch from GPU to CPU for rendering. I can't even see that option in rendering tab though. The fire works just fine otherwise, and i followed the tutorial exactly. Any ideas why the rendering won't work? Thanks in advance!
That tutorial, as you can see here, is for 2.73, and since then the Blender UI changed a bit, you can find that option in "file=>user preferences=>system" now (it's called "compute device").
You could also download an old 2.73 from the Blender website, to make it easier to follow the tutorial.
- be sure to use "cycles" render before creating the "quick smoke" setup.
- save the file in order to enable the cache settings
- before rendering, run the simulation from the start (frame 1) since it could need recalculations
- if something in the simulation seems to be stuck after some settings change, try also to delete (and thus rebuild) the cache
Also, on the above page you can download a "finished" .blend which could help you understand better.
