Crash on 'TransformParticleMesh' when setting Particles in PlayMode

-

How to reproduce:
1. Open the “ReproProject.zip“ project
2. Open the “SampleScene“ scene
3. Enter the Play Mode

Expected result: No crash
Actual result: Crash

Reproducible with: 2023.1.0a20 (be935afddb32), 6000.0.13f1, 6000.0.57f1, 6000.2.4f1, 6000.3.0b1

Reproducible environment: macOS 15.6.1 (M4 Max), Windows 10 Pro (22H2), Windows 11 (Reporters)
Not reproducible environment: No other environment tested

  1. Resolution Note:

    In the provided reproduction project, the particle system ends up trying to process 923911 mesh particles, with each mesh containing 768 triangles (515 vertices, 2034 indices), resulting in a total of 475,814,165 vertices and 1,879,234,974 indices.
    You could try reducing the total number of particles, or using a simpler mesh like a Quad.
    Additionally, if possible in your context, you could try using VFX Graph that is better suited to handle large particle count (GPU simulation update, instanced drawing of particles)
