How to extrude/stretch volume on Y axis


i-d

Recommended Posts

If you are trying to do an actual Aurora Borealis FX, I'd suggest you go on a different way.

 

You can make the geo you want so it looks like the ribbons in the sky and then convert it to volume with a bunch of attributes and gradients for color, noise and the like.

 

Does that make sense?

I'm not specifically after aurora effect this time but more how to approach this

problem of volume stretching. I think I maybe have a workable solution with

a little bit of volume vop and volume advection. Lets see how it goes.
