Smoke container boundary wrap around

[mani]

Hi,

is it possible to somehow make the boundaries of a smoke container wrap around instead of just collide, so smoke that moves beyond the z+ boundary enters with the same velocity in z- and vice versa?

I want to create a tilable smoke field and that would be simpler and i guess also better looking than to do it in comp.

Thank you

You might have some problems at the corners and edges if it's going slow, but I would use a wrangle to manually wrap around the fields. Not sure how yet, but find the min and max of each axis, then set my artificial boundary one voxel less. Then, at that new boundary I'd do a stupid simple

(pseudo code)
 

if density @ edge.highx > 0
then density @ edge.lowx & density @ highx = 0...

and on and on for every combination of high/low and x,y,z for every field just as if I'd wrap around on a 2D screen.
