#ttp 318670 - UE4: RENDERING: FORTNITE: Write HighResScreenshots to OpenEXR (ideally PSD as well) #proj Engine #branch UE4 #summary Added OpenEXR library, added OpenEXR format to ImageWrapper Module, Changed highres screenshot code to save with image wrapper. #Add OpenEXR support (for writing) to ImageWrapper module. (enabled for windows builds only) #Add added option to highres screenshot code to choose to output as hdr / openexr #Add 2 new visualisation modes, scene depth world units and custom depth world units. #add cvar 'r.BufferVisualizationDumpFramesAsHDR' to enable hdr export from console. #change FRCPassPostProcessMaterial can specify an override output texture format if required. #add SaveImage function to FHighResScreenshotConfig [CL 2252882 by Allan Bentham in Main branch]
