Hello!
Can someone please explain why the shadows gets lighter when copy the selection, and pasting in again?
I want the shadows to be as the pasted in version, (shorter and more suttle) but can I do that by adjusting some Alpha-layers? Its rendered from blender, look my video 

Thanks!

Why do you do that at all and not render the image with object and shadow separate to begin with? 

Anyway, a pixel of 50% opacity, selected 50% and copy/pasted will result in a pixel of 25% opacity.

No, copy/paste does not reduce the Opacity by itself, the active Selection when copying makes the difference. 

If you Select > All, Copy and Paste the opacity will not be reduced. 

 

Why do you copy/paste and not simply use the Smart Object as is (and add a Layer Mask if necessary)?
