3D Shadow

Apr 18, 2012 4:39 AM

A dice or any cube mounted with textures in a 3D environment in AE generates shadow? If yes, what I´ve to do?

    Could you re-post your question and provide a proper explanation of what you are doing? No offense, but this is exactly the kind of "mumbling at the screen" question that usually nobody can answer because we are not seeing what you are seeing.

    Shadows will only appear on 3D layers. There is no such thing as a shadow matte/ shadow catcher in AE. If you need shadows either make your BG layer a 3D layer as well or create a duplicate of your dice comp all in white/ greys with shadows, then apply it as a 2D comp on top using multiply blending mode.

    Attached is a CS5 project file with a precomped 3D cube casting a shadow on a solid floor.

    Create a 100 x 100 pixel solid, and a comp size solid. Make them both 3-D layers. Rotate the comp size solid 90° on the X axis. Position the comp size solid at the bottom of the small square solid. And a light and a camera. Position the light so it shines down and at an angle to the small square solid. If no shadow appears, select both solids and the light then press the a key twice. Use should see material properties and properties for the light.

     

    Select cast shadows on the light, cast shadows on the small solid, and accepts shadows on the large solid.

     

    There you go. The basics of how to cast a shadow.
