Eric, as usual, is right. This is best handled in a paint program. But just in case you don't have one, here's an RDS bug that can finally be used for good instead of evil!

The above illustration shows a glowing sphere partially obscured by a rectangle, but when the rectangle's transparency is set to 100% ~~~ viola ~~~ the object is visible, but the aura is still blocked.

Hope that helps.
