It's ok on a screen but in final output picture ("include alpha" on) the shadows turns into some weird interlaced appearance with the same horizontal 1pix strokes in normal , depth and "clown" passes.

Beside the passes itself ignore alpha in the materials completely. It's very disappointing and makes them pretty useless. I hoped to do some orto renders of tree models and looks like Keyshot can't do proper foliage at all in the passes.
win8.1-64 Keyshot6 Pro , Zbrush bridge , To reproduce the problem just put some texture with alpha on something .
I have the same problem in Keyshot 6. The same scene in Keyshot 5 doesn't have the problem.
If I save my rendering as a png, tiff or psd with an alpha channel, then the jagged edges occur.
I have discovered, that the problem goes away, if I use a coloured or dark background instead of a white. But that does not give me the transparent shadows I need.
This is probably caused by the aliasing.
Did you try using max samples/time rendering mode instead.
That should remove the jagged edge contour.
