Hi everyone! I was looking at some old After Effects work that I did, and came across a photo that I had added “3D” text onto with a fake shadow. I decided to recreate the effect in Blender with cycles, and decided to create a quick tutorial!

In this quick tip, we’ll go over how to break apart your scene into separate render layers so that we can properly composite the shadow pass onto the 2D image. We’ll also go over using the “Box Mask” node to mask out areas of a render that we want to remove. In the end we’ll composite the shadow pass, and then the 3D text onto the 2D image.
