# RHICommandList::SetBlendState

```cpp
virtual void SetBlendState(const BlendState& state) = 0;
```

设置颜色混合状态。控制源颜色和目标颜色如何混合，影响最终输出像素的颜色值。

**参数：**
- `state` - 混合状态结构体（包含 alphaToCoverageEnable、independentBlendEnable、renderTargets[] 等）

**返回：** `void`

**异常：** 无

**线程安全：** ❌

**复杂度：** O(1)

**示例：**

```cpp
BlendState blendState;
blendState.alphaToCoverageEnable = false;
blendState.independentBlendEnable = false;
blendState.renderTargets[0].blendEnable = true;
blendState.renderTargets[0].srcBlend = BlendFactor::SrcAlpha;
blendState.renderTargets[0].dstBlend = BlendFactor::InvSrcAlpha;
blendState.renderTargets[0].blendOp = BlendOp::Add;
cmdList->SetBlendState(blendState);
```
