Root Cause

The particle system in VFX Graph exceeds the allocated buffer capacity due to excessive particle count or lifetime.

VFX 图形中的粒子系统因粒子数量或生命周期过多而超出分配的缓冲区容量。

Workarounds

  1. 75% success Reduce the spawn rate or particle lifetime in the VFX Graph. For example, set 'Spawn Rate' to 50 particles per second and 'Lifetime' to 2 seconds. 
    Reduce the spawn rate or particle lifetime in the VFX Graph. For example, set 'Spawn Rate' to 50 particles per second and 'Lifetime' to 2 seconds.
  2. 85% success Enable 'Capacity' auto-resize or increase buffer capacity in the VFX Graph asset settings under 'Particle' > 'Capacity'.

中文步骤

  1. 在 VFX 图形中降低生成速率或粒子生命周期。例如，将“生成速率”设置为每秒 50 个粒子，“生命周期”设置为 2 秒。
  2. 在 VFX 图形资源设置中启用“容量”自动调整或增加缓冲区容量，路径为“粒子”>“容量”。

Dead Ends

Common approaches that don't work:

  1. Increase the 'Max Particles' property in the VFX Graph inspector to a very high value. 40% fail

    Simply increasing max particles without optimizing spawn rates or lifetime can still cause overflow if the system is poorly designed.

  2. Disable all VFX Graph components in the scene to see if the error disappears. 60% fail

    This only masks the issue; the root cause (buffer overflow) remains and may reappear when VFX is re-enabled.
