Questoin for multipass shadow for After Effects.

[Josh J. Johnson]

I tracked a aerial shot with syntheyes worked great. Brought into cinema added some 3d elements and shadows. I have a plane for my floor so you can see the shadows. I applied my background to the plane along with a compositing tag “not seen by camera” and “compositing bg” on.

I can’t seem to make it work in AE? I can say just render out the whole image in Cinema with the backdrop and everything looks fine but then I can’t isolate things in AE.

Any help would be greatly appreciated. I searched the forums and I think I did everything that was suggested. Also I can do this in photoshop with no problems. In photoshop I just cut out my elements with their alpha place them on my photo bg and add shadow pass on top with multiply blend.

So basically I can get my stuff in AE and everything tracks perfect looks great but I have no shadows?

thanks

I don’t understand why you aren’t able to do it the same way in AE that you’re doing it in PS.

Hey Adam thanks for the reply. It seems everything works minus the shadow on the ground?

I tried the exact same setup I did in PS with no luck. I tried the ground plane(shadow catcher) with seen my camera on and off.

In ps I would extract my elements put them together then add the shadow pass on them not the same with AE?

thanks again

Here is a picture Adam to better show my problem. As you can see my shadow catcher is all white? How and why I ask lol. What I’m expecting to have is my shadow catcher be invisible besides the shadows? I tried nearly every option that I can think of.

Try changing the white layer with the shadows transfer mode in AE to Screen or Multiply.
