Niagare system inside a pipe

Hi!
I don’t think it’s possible but perhaps there is some workaround.
I have a pipe (but could be any other mesh empty inside). I would like to move particles inside this mesh. For example, the particle enter in the pipe and go out in the other side.
I thought that would be possibile using GPU Distance Fileds inside collision, but even using this method the particles don’t collide with my mesh.

There is some tricky solution? Actually I don’t see any :slight_smile:

If your pipe has collision, and you set the emitter to use collision, it should work.

If you go inside the pipe as the player, can you get out the sides?
