Trying to make a 2D smoke element have 3D volume.

Hi there, 

 

I have a 2D smoke element (it's a smoke cloud MOV with alpha) that I would like to have panes of glass intersecting vertically and horizontally.  Normally I would just create the smoke/cloud with something like Nebulosity to have a real volumetric cloud, but the client has a specific smoke clip they want.

 

Is there a trick to adding voume to a 2D layer?  I thought about layering it each with 20% transparency and off-set just a bit in Z space. Then the glass panes would be more visible in front and slowly fade further back.  But, then I'm getting sharp edges when the pane intersects the smoke layers.  If I could round the layer or bend it that could work, but wonder if there are better ideas out there.

Any thoughts?

Thanks!
-Stephen

I went back to my plan of layering with masks and it ended up working out just fine.

If you end up needing to do this for a lot of layers, it might be worth exploring CC Particle World.  This tutorial I made a while back shows how you can fly down a tunnel of particles.  There will be steps you're not interested in, but the same principle applies.

You could probably have converted it to some sort of point cloud using e.g. Trapcode Form using the image as the texture for color and opacity.

I knew there was a plugin that could do it.  Unfortunately I don't have Trapcode but I'll think about that the next time this comes up.  Thanks for the suggestion!
