Problem with OpenGL accumulation buffer

[GroundUpEngine]

I have been messing around with basic effects in OpenGL, the effect I have had problems with is motion blur via the accumulation buffer. When I render transparent treetops and fog in the scene, then add a motion blurred object (different part of the scene) all the treetops seem to be unaffected by fog standing out with a darkened colour.

Well that's strange. It seems to me that those trees give you all sorts of trouble xD Sorry to report that I have no experience with this OpenGL effect, so I'm absolutely useless.

Project's pretty dead.. but I fixed the main problem being rendering the transparent part of the trees with techniques like manual Z sorting, but this problem is just another bug due to the limitations of either the API or my knowledge of the API.

Oh god. I thought since there were no responses that this was a relatively new thread. Need to check dates....
