Question by unity_7DydZGRnswkF7w · Dec 14, 2019 at 02:16 PM · particlesparticlesystemparticle system

How to align initial rotation of each particle to the particle system transform?

I have a particle system with simulation space set to "World". I want particles to be aligned with the particle system transform when they are emitted. I also don't want them to rotate together with the particle system after they have been emitted, which is what happens if I set render alignment to "local". How can I achieve that?  


Here is what I'm trying to do: I have an object moving through scene. I'm creating a particle trail behind this object, that shows how the object was moving and rotating. Each particle has the same model as the object, but with a different material. So i need these particles to be oriented the same way the object was oriented when it was passing that point in space.
