Hi,
I currently have a scene that is lit by Mental Ray Sun and am getting very nice results but i have now added a particle effect meant to mimic smoke.
In the viewport all my particles have correct opacity but when rendered the parts of my particles that are meant to have an opacity on them turn up black. I tried the suggested solution that worked for vicki with her opacity planes not rendering Properly by turning off Aeriel Perspective but this did not help.
If Adding any Screen shots or my file would help I will upload these asap, but any suggestions or tips would be greatly Appreciated.

Thank You
