Depth Map
SO.
I have a bunch of illustrated elements with alphas applied to planes in 3d space. However, the alpha channel recognizes this, but the depth map output is recognizing them as planes, not as alphas. Is there a way to tell the depth map output to recognize the alphas? Or am I going to just use the alphas from the individual objects and use them as mattes for the depth map in post?
Suggestions?

there are a couple DOF plugins that support Alpha and transparency as well in the depth map

or as you say use the alpha map and the depth map together in post

Thanks.
The only problem is when stuff overlaps, and then you matte it in post, you get some really strange results because mattes kinda checkerboard onto each other.

Here’s a trick I picked up a while ago on another forum:
“Place an Omni light at the camera position. Check Ambient Illumination and uncheck Diffuse and Specular. Turn off shadows and all other lights. Set the Falloff to Linear and the distance to the farthest thing away you want depth defined at 100% at. You can pull out the control handle on the light in the viewport interactively. Turn off all textures and render. To get depth maps where the foreground blurs just move the Omni Light to the center of focus and adjust the falloff. You can also play with Inverse Square and other falloffs to get more focused or different falloffs on the depth map. Whether they have any correlation to real lenses I am not sure..
