Smoke and fog problem

[agep]

I am having problem with the sprite system. I am unable to create a depth map when using a smoke emitter and fog. I looks like the emitter ignores the fog, and stays bright white no matter what. Using the depth Buffer doesn't work either, the Depth Buffer doesnt render the smoke at all. Can anyone take a look at this problem before I report it? I might have missed something elementary.

 

I could fake it by giving the smoke a grey tint, but it would not be the best solution, since the camera is going to be moving

I'm stumped on that one. It's probably greatly complicated by the fact that the particles are transparent.

 

What will you be doing with the depth map?

Hair with an image with alpha (leaf) renders fine though

I am going to use the depth map to make Depth Of Field on a Thomas and friends animation test I am currently rendering. Reason why I don't use A:M's own DOF, is because of the increased rendertime (on top of the 15hr per frame sequence) and the lack of control in post. With a depth map I can control where to set my focal point in post

How do you get anything done if your renders take 15 hours per frame? I can't imagine doing an animation

report it then and see if it can be done.

 

I wonder what is the "depth" at a 50% transparent surface? There is no single right answer.

For now I'd say render the smoke separately and approximate the DOF in post.

Part of the issue maybe that if I remember correctly that sprites are rendered last and therefore would be in front of the fog

Just curious... is it any different if you bake the sprites?
