It's been a little while i'm using Blender now, but I never did try to simulate smoke yet.

I have to work on titles for a little movie and I was wondering if it was possible to make a picture projection on a smoke simulation (using Cycles) and if you had some directions to handle this?

Thanks!

    $\begingroup$ What render engine are you using? In Cycles I would plug the image into the color of the smoke using camera or window coordinates. $\endgroup$

You can use a spot light and add an image as texture to it.

In Cycles (I don't know about BI) you can use the standard smoke node setup (without the fire nodes) and replace the color attribute node with an image texture node using window texture coordinates.

Here is the render:

For comparison, here is it using the actual smoke color (before replacing the color attribute node):

And here are the nodes:

If your image has an alpha channel just multiply the density attribute node by the alpha channel before giving it to the density of the shaders.

  • $\begingroup$ Thanks PGmath, that's a nice solution but I forget to mention that what I'm looking for is to distort the picture on the smoke mesh (projection), so cegaton's answer is perfect for me :) $\endgroup$

Also, have a look at the UV projet modifier.
