Hi everyone, I really need help with my setup. Sorry for my english.

I'm working on a aurora borealis. View from space, so the aurora is pretty huge.

I'm working with points in a huge sphere (of course only in the north pole where the aurora is, I have a texture map for that). To be able to work with volumes without stepping problems in a small scale, I decided to divide the whole sphere into small sections, then moved all the points in a specific section to 0 in Y using a ‘Point SOP’ changing the P.y of each point to 0. That gives me a flat cloud of points. After that I used fluid source and volume vop to create the pattern I want with a color ramp and everything.

My problem is when I'm trying to move the volume box / density back to where the origin points where. It will need to move it back in Y direction, but because the original position used to be bended (part of a big sphere), I would need to bend the volume, right?

Do you think I should approach this in a different way?

Any help is much appreciated. Thanks
