I just need to rotate emitter. I have to use it in both horizontal (xy) and vertical , thats what I need exactly. However when I rotate it, 2D mode doesnt work properly and particles scatter around. As I said the only solution was changing 2D mode to 3D, but I dont prefer that for some reasons. So, please give me an advice, and the example scene is again von karman sample. I really need it and it shouldnt be so complicated, thanks a lot.
If you rotate the emitter around the Y axis while in 2D mode, particles will of course scatter around since you're emitting them outside of the XY plane where the simulation happens. 2D mode will only perform the simulation using 2 dimensions (X and Y), will completely ignore motion/forces/collisions in the Z axis. In 2D mode you're supposed to rotate the emitter in the Z axis only.
If you want to rotate the emitter both around the Y and the X axis but still want the particles to react to colliders around it in 3D, you need to use 3D mode. There's just no way around it.
