Issue ID




Two independent Particle systems appear to be using the exact same seed for randomisation



How to reproduce:

1. Open attached project
2. Open scene particles.unity
3. Play the scene
- Note how the coloured particles and the black particles appear to be moving in the exact same patterns
- This happens even if the particles aren't parented/childed to each other
- The particles in both separate systems should be moving in different ways

- Reproduced in Version 5.4.0b11 (323b0238353b), Version 5.4.0b6 (2c3d6b93e789)
- Not reproducible in Version 5.3.4p1 (e89f89413a91)

    Still there in 5.4.0f1. You seriously think this is a proper Release Candidate without fixing this bug?

    Just ran into this after updating from 5.3 to the latest beta release. Was working fine in 5.3. Currently using 5.4.0b25

    This behaviour still occurs in 5.4.0b22 and can be quite annoying so it would be nice if it gets fixed soon!
