# PS5 支持
|
|||
|
|
|
|||
|
|
返回 [[Platform]]
|

|
|
|
|||
|
|
## 概述
|
|||
|
|
|
|||
|
|
PS5 平台的修改相对较少，主要是 Feature Level 定义和 GBuffer 格式的平台差异处理。
|
|||
|
|
|
|||
|
|
## Feature Level
|
|||
|
|
|
|||
|
|
在 `Public/Platform.ush` 中为 PS5 添加 SM5 Feature Level：
|
|||
|
|
|
|||
|
|
```hlsl
|
|||
|
|
#elif PS5_PROFILE
|
|||
|
|
#define FEATURE_LEVEL FEATURE_LEVEL_SM5
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
## GBuffer 格式适配
|
|||
|
|
|
|||
|
|
Specular GBuffer 在 PS5 上保持标准格式，仅在非 PS5 平台降级为 `PF_A8`：
|
|||
|
|
|
|||
|
|
```cpp
|
|||
|
|
// SceneRenderTargets.cpp
|
|||
|
|
#if !PS5_PLATFORM
|
|||
|
|
SpecularGBufferFormat = PF_A8; // 降低精度节省带宽
|
|||
|
|
#endif
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
参见 [[GBuffer修改]]。
