Syntax

UPROPERTY (EditAnywhere, Category=PostProcessMaterial)  
uint8 bDisablePreExposureScale: 1

Remarks

Disable pre-exposure scale in post process materials (multiply by View.OneOverPreExposure on inputs, View.PreExposure on output). Useful for materials that don't care about the absolute intensity of SceneColor (for example, a blur), simplifying custom HLSL and saving some performance. Or useful for non-color UserSceneTextures (for example, mask, matte, modulation, offset, or ID textures), where pre-exposure scale is undesirable. Pre-exposure scale can be manually reapplied via custom HLSL if needed on specific inputs or the output.
