How to set the curve about the mesh type particle system, so that the model can rotate according to the specified axis.
At present, the rotation speed can only specify one-dimensional number(named angle), not XYZ three-dimensional vectors.
It would be tricky. You would have to modify the velocity graph to be a cos and sin graph on the other two axis. eg want to rotate around Y axis, modify the X and Z.
Not sure it will get you the end result you want due to the random spawning?
Thank you for your answer，The method you are talking about can only make the model move in a circle along a radius。The effect I want to achieve is to have a model implementation rotate along an self axis.
Oh sorry, I see what you mean now. Unfortunately this is not supported.
