Artifacts on the edges with smoke simulation.

Hi!
I hope i guessed the sub-forum correctly (:

I have a standart smoke simulation, sun lights whout shadows, collisions material is just basic too.
And here is the problem:

It seems that edges are not affected by AA if they cover the smoke.
I just do not know how to fix it.
Any ideas?

Okey, the answer was to enable Ray transparency instead of Z in the smoke (domain) material.

That has its own issues. Instead, try leaving it as Z-transparency, and under material options, turn on “Full Oversampling”.
