```c++
//BlueRose Modify
FGBufferData SamplerBuffer = GetGBufferData(UV * View.ResolutionFractionAndInv.x, false);
if (SamplerBuffer.CustomStencil > 1.0f && abs(SamplerBuffer.CustomDepth - SamplerBuffer.Depth) < 1)
{
// OutColor = SampleSceneColor(UV);
OutColor = TonemapCommonPS(UV, InVignette, GrainUV, ScreenPos, FullViewUV, SvPosition, Luminance);
}else
{
OutColor = TonemapCommonPS(UV, InVignette, GrainUV, ScreenPos, FullViewUV, SvPosition, Luminance);
}
