How do I change the axis of rotation on a mesh particle in Unity 4.1?

I recently upgraded from 3.5 to 4.1. I had a long mesh particle rotating around the Z-Axis in 3.1. When I upgraded to 4.1 it changed to rotate around the Y-Axis. How do I change this? I’m using the Rotation over Lifetime to rotate.

I think it can be done in code. There’s an undocumented property on a ParticleSystem.Particle called axisOfRotation, which you can set. You’d have to do it per-particle however, so somethign like this:

ParticleSystem.Particle[] myArray = new ParticleSystem.Particle[256];
int count = MyParticleSystem.GetParticles(myArray);

for(int i = 0;i < count;i++)
    myArray*.axisOfRotation = Vector3.Forward;*

I hope this helps, I found this post searching for a solution to my own problem (setting particle rotation on more than 1 axis) and thought I’d share what I have so far in case it was helpful.

This is one of the highest viewed questions… I am new to Unity and only have used version 4.1. Correct me if I’m wrong, but the earlier versions looked like they had editable values for all three axises in the “Rotation over Lifetime”. I would love to know the answer as well.

There is no solution for this in the current version (4.5) of Unity.

It’s been 2 years and still nothing…

I just ran into this problem.
