Crash on ParticleSystemTrailGeometryJob::RenderJobCommon when changing trail Mode change with a large particle count
Reproduction steps:
1. Create a new 3D project
2. Import “CrashReport.unitypackage“
3. Enter play mode
4. Select the last GameObject in the Hierarchy window
5. In Emission increase “Rate over Time“ to around 30000
6. Increase “Max Particles“ to 1000000
7. In trails, switch “Mode“ between Ribbon and Particles a few times
8. Change the values in steps 5 and 6 and repeat step 7
Alternatively:
1. Open the “ExplorerRepro“ project
2. Select the particle system in the scene and increase the “Playback Speed“ to 10
3. Open the Explorer window and run the test
4. If it does not crash in 30 seconds, remove the existing particle system and add a new one
Expected result: Particle system runs
Actual result: Particle system crashes when changing values
Reproducible with: 2022.3.65f1, 6000.1.10f1, 6000.2.0b10
Couldn’t test with: 6000.0.54f1, 6000.3.0a3
Reproducible on: Windows 11
Not reproducible on: No other environment tested
Notes:
The crash could not be reproduced locally by CQA for Unity 6 versions, but the crash was reproduced on 6000.2, so the problem is likely not fixed for Unity 6 versions
The crash is very inconsistent, can crash right away or still work after 30 minutes of trying
