How to create and render clouds in blender cycles I am creating an outdoor scene and need to create 3d clouds. What is the best way to go about this in blender cycles. I know you can't use the cloud generator addon since cycles doesn't have support for volumetric shading. Any help is apreciated.
Since the initial commit in January 2014, cycles has had volume support.

You can get a development version or any version newer than 2.70 to use it.

To render clouds with it, try sculpting a cloud shape (dynamic topology is useful) or modeling a low poly cloud with a subsurf and a displace modifier:



Smoke simulations look better, but will require more computation time to be baked.

For the cloud material, use a volume scatter node:



Result:





Make sure you set the scattering bounces pretty high in Render settings > Light paths if you want bright, fluffy clouds.
