live stack group and masking on member layer

Recommended Posts



when using a mask layer applied to a member layer of a live stack group, the mask behaves strange:



If the mask value is 255, the pixel is inlcuded and shown.

If the mask value is bewteen 0 to 254, the pixel is not shown.


Values between 0 and 254 should lead to an pixel with accoring alpha.

You can try at your own by adjusting the slider of the levels adjustment.

You can see that it only affects which pixels are shown (when reaching alpha 255).


I might be wrong with my expectation ;-)
