Rendering smoke in Cycles?

Question

I am trying to render smoke in cycles, but the relevant blender manual page is designed for Bender Internal. I have everything set up except for the material.

I imagine you would set up the material nodes something like this:

enter image description here

But the problem is that there is no Voxel Data texture node, ans I am not sure what kind of shader should be used.

Is smoke in Cycles simply not supported yet? Or do I need to go about this a different way?

You can do it now in 2.71 :) "Blender 2.71 Feature Preview: Smoke and Fire in Cycles" https://www.youtube.com/watch?v=oSiV5gg_lCs — Oskar Świerad, Jul 02 '14 at 07:51

As of version 2.73 from 2015:

Make sure render engine is set to cycles (BI wouldn't create the required cycles materials)
Select the object you want to emit smoke
From the menu Object/Quick Effects pick Quick Smoke

After that a material has been created that looks like:

In order to also emit flames it can easily be extended to:

Note that the attribute names have to be exactly as they are show 'color','density' and 'flame'.

Important settings for the Domain object (besides higher-resolution):

Important settings for the Flow Object:

Add a procedural texture and animate some properties to animate the flames.

You can do it in Blender 2.71 or newer (which added support for volumetric data in Cycles).

Make a group in nodes that looks like on the screenshot below. It's very important that you make the two "Attribute" nodes exactly like shown on the screenshot - "flame" lowercase and "density" lowercase - because it refers to data in the object.

The material itself: material screenshot

Now use this material on smoke domain. That's all :)

I took this setup from this video: https://www.youtube.com/watch?v=oSiV5gg_lCs

From the Cycles Roadmap:

Probably the first release with Volumetrics will be 2.69 or 2.70.

"Probably" being a keyword - though I can say with certainty that it will not be in 2.69, and I doubt there'll be anything for 2.70 either. – Greg Zaal Sep 05 '13 at 07:31

This answer is now outdated. Smoke is supported in cycles starting with version 2.71. It is still limited to CPU rendering (as of version 2.76) – Dec 25 '15 at 18:55
Smoke rendering is supported in GPU starting with version 2.77 – Mar 21 '16 at 15:58

Volumetrics and smoke are not currently supported by Cycles. There are some experimental builds that will support rendering static volumes, but not voxels, yet.

Version 2.70 is reported to support volumes, and voxels (for smoke) will come later.

It might be clearer to say that the development version of blender as of this commit cycles has volumetric scattering support, and that it will be in 2.70. – gandalf3 Jan 16 '14 at 22:20
Ah yes, quite right. – Matt Jan 16 '14 at 22:29
blender 2.73: voxels can now be rendered with cycles (CPU) and static volumes can be rendered with GPU and CPU – Bithur Feb 08 '15 at 15:23
