3d layer – Casts Shadow for specific object
Hello I have a 3d layer with Casts Shadow Effect this 3d layer interact with some compositions inside the composition where I have 3d layer.
This is the screenshot
As you see there is composition Logo. So that composition has 2 objects logotype and text. What I want is to have a shadow just for Logotype but not for the text. What is the best way to leave object in the composition but hide it from the Casts Shadow Effect in the main composition?..
This is the screen shot of Logo composition which is inside the mail composition with the 3dlayer
Thanks for any help! -

Duplicate the composition both in the project panel and in the Current Main composition, leave the text on one and the logo on the other. Turn of cast shadows for the text’s one.

Yes I can do it but inside Logo composition I have animation between logo and text… If I understand you correctly I have to split that animation for 2 different compositions? Or I’m wrong? If I have to split them it’s a lot of job… Is it any easier way to do so?..

I doubt it is a lot of work. You’re probably just not familiarized with copying with relative properties link (to retain animations and changes) and track mattes(to keep interactions). Because you can easily remove each of them from view without losing anything.
Unless you have some very complex blend mode interaction, its a matter of seconds.
If you want an “easier” way, perhaps unprecompose the logo and text to the main composition, and change the text’s cast shadow option. But as I imagine, this will create other issues.

A lot of Ae users run into a problem where they try to mix 2D and 3D layers, which interferes with intersections and shadow-casting. If you don’t need full 3D intersections (occlusions), we can hijack this idea and use this to our advantage.
Make the text the very first layer, index #1, in the comp. Insert an adjustment layer as the second layer, index #2.
This adjustment layer will break 3D intersections, because it’s a 2D composite of all the layers below it. That means that the text layer #1 can be affected by the light, but cannot cast shadows onto the shadow-catcher.
