根因分析

GameObject 的实例化和渲染之间材质属性块或着色器关键字不同，导致 GPU 实例化批次中断。

English

Material property blocks or shader keywords differ between instantiation and rendering of a GameObject, causing the GPU instancing batch to break.

解决方案

  1. Ensure all instanced objects use the same MaterialPropertyBlock values by assigning them in a single batch: `MaterialPropertyBlock block = new MaterialPropertyBlock(); renderer.GetPropertyBlock(block); block.SetColor("_Color", Color.red); renderer.SetPropertyBlock(block);`
  2. Disable per-instance shader keywords by removing `#pragma multi_compile` variants that vary per object, or use `Shader.EnableKeyword` globally.
  3. Use `Graphics.DrawMeshInstanced` with a shared material and property block array instead of individual renderers.

无效尝试

常见但无效的做法:

  1. 40% 失败

    Disabling GPU instancing globally reduces performance and doesn't address the root cause of property block mismatch.

  2. 60% 失败

    Setting material.renderQueue manually often ignores the underlying shader property block differences.

  3. 50% 失败

    Using MaterialPropertyBlock.Clear() before every draw call may cause flickering and still not synchronize with instancing.
