I’m trying to simulate camera exposure by using a SceneCaptureComponent2D to additively render to an RT each frame, then applying post-process before exporting. The problem is, I need to be able to set Composite Mode to Additive for the exposure effect to work, but the only Capture Source that allows Additive is SceneColor(HDR). I’ve tried exporting with EXR but this also doesn’t work, so I think it has less to do with HDR or filetypes.
When using SceneColor mode, the result is the foreground is entirely transparent, and the background is entirely white (I would upload a screenshot but the site isn’t working). I haven’t been able to find a way to override this behaviour either, but this is only a problem when exporting HDR data.
Any help would be greatly appreciated.
