Description

The Vector Field Initial rotation module will have the same rotation for all instances of the same emitter. This is a regression from 4.22.

Steps to Reproduce
  1. Create a new particle system
  2. Add a New GPU Sprites module from Type Data
  3. Add a VF Init Rotation Module
  4. Set the Min Initial Rotation to 0.0, 0.0, 0.0 and the Max Initial Rotation to 1.0, 1.0, 1.0
  5. Add a Local Vector Field module
  6. Set the vector Field and Intensity values to something easily visible.
  7. Place the emitter in the a level and duplicated it a few times.

RESULT

The emitters will all have the same initial rotation, and follow the same path through the vector field. In 4.22 each duplicated emitter would take a different path.
