public static void SetTierSettings (BuildTargetGroup target, Rendering.GraphicsTier tier, Rendering.TierSettings settings);


指定したプラットフォームとシェーダーハードウェア層の PlatformShaderSettings の設定が可能になります。

If the platform you are tweaking is an active build target, the shaders will reload so you can see the results immediately. If `PlatformShaderSettings` is set to tiers that are not the same, then tier variants will be generated for the shader even if `#pragma hardware_tier_variants` is missing. You can only set Graphics Tiers in the Built-in Render Pipeline.
