how can i make the particular to share the same 3d space than the rest of the 3d layers? I mean am i doing
something wrong, because when i put the particular emitter to the exactly same Z depth with another layer,
they are still not in the same position in the z depth when moving the camera. I'm getting quite frustrated with guessing. I
find it also annoying, that the layers do not automatically hide the particles when they are in front
of the emitter in z space (you can do something with obscuration layers, but they're quite limited).
