bOutputAlpha

Should we accumulate the alpha channel and write it into the resulting image? This requires r.PostProcessing.PropagateAlpha to be set to 1 or 2 (see "Enable Alpha Channel Support in Post Processing" under Project Settings > Rendering).

bool bOutputAlpha

Remarks

Should we accumulate the alpha channel and write it into the resulting image? This requires r.PostProcessing.PropagateAlpha to be set to 1 or 2 (see "Enable Alpha Channel Support in Post Processing" under Project Settings > Rendering). This adds ~30% cost to the accumulation so you should not enable it unless necessary. You must delete both the sky and fog to ensure that they do not make all pixels opaque.
