Hi Colin, thanks for you reply! Unfortunately this won't work. I have "dead" alpha samples pretty much everywhere, so also in front of the element I would like to keep. Doing a DeepHoldout results in a pure black image. And with a 2d DeepHoldout I loose my deep samples anyway. Using the DeepMerge set on holdout has the same result. Also I couldn't find a "remove empty pixel" checkbox, do you mean the "drop hidden samples"? So I guess there is no way of getting rid of deepsamples without writining my own DeepOp?
