NullReferenceException is thrown upon entering Play mode when "3D Start Size" is disabled in Particle System properties

Package: Burst


How to reproduce:
1. Open the attached “Particle Burst Test” project
2. Enter Play mode
3. Observe the Console

Expected result: No errors appear
Actual result: NullReferenceExceptions spam the Console

Reproducible with: 1.7.0 (2020.3.37f1), 1.7.3 (2021.3.8f1, 2022.1.12f1, 2022.2.0b4, 2023.1.0a5)

Reproducible on: Windows 10

  1. Resolution Note:

    This is not a Burst issue. I've attached a native debugger and caught the crash, and it looks like the x and y buffers in ParticleSystemNativeArray3 for particles.sizes are only set when "3D Start Size" is checked for that particle system. So it's probably expected behaviour, but if it's not, you'd need to contact the particle system team about it.
