Alan's Cloud Generator (beta)


example2.jpgWell, it appears that Blender may have reached another milestone in the pursuit of 3D clouds!

Alan (aka RipSting) writes:

I've been doing a lot of atmospheric modeling lately and wrote a script that generates some cool interactive volumetric clouds! Not only can you see the shape of your clouds in the interactive 3D window, but you can animate their properties with IPO curves.


When you're done automatically generating points, you can edit them and delete the clouds that you don't want. Then, it turns the clouds you DO want into faked volumetrics. I say fake, because it will only render correctly from the camera's perspective, so it won't work that well yet with extreme reflections.

Here are some sample renders and animations:


You can download the latest version of this exciting script and keep up with the latest development news and discussion at the blenderartists discussion thread.


  1. Hi All,
    I'm excited to see this here on BlenderNation! I will be uploading a release candidate within the next week with many improvements in ease of use, previewing, and cloud shaping.

    Raffy: The picture isn't loading for me, but if you're referring to the cloud fly-through animation, it's a result of compositing with nodes. The clouds were rendered separately from the water, and the alpha channel didn't quite render as I had hoped.

  2. I just tried some inhouse-visualisation with influence of environment-maps. Is this a plugin? Where can I download it? is it in svn? looks really great... thanx.

  3. Something else I saw in the first animation.
    When Suzanne is falling through the cloud, I don't see any shadow from her in the cloud.
    Is this going to be fixed?

  4. AHHHHH! I have been waiting for this. It would still be nice if it wasn't faked but as long as it looks good and is easy to use....

  5. Well, it is an amazing step ! Thanks a lot !

    I was thinking about purchasing Vue 6 to get volumetric clouds, but maybe Blender will do this before I will have the money for purchasing Vue 6 !o)

  6. Great timing. I have just started working on an animation job that requires flying from space down to earth and I was wondering if I was just going to have to use a cut scene to skip the clouds. Now, maybe not. Thanks for the great script
