Prevent Projector From Going Through Shapes

I feel like I'm missing a simple switch, but I have a text being projected through a Camera3D node, and currently it projects onto three separate 3D shapes (2 with Duplicate3D nodes), although the projection is passing through each shape and fully onto the background. So I was wondering if there was a way to if the shapes in front essentially "block" the projection from hitting behind it or if there was a separate way to project the text. I can provide screen shots if necessary.

Project as texture and use a Catcher.

I tried the Catcher node on the shapes with the Camera3D projecting as a texture, but the projection still went through the shapes. Is there an additional setting on the Catcher node that prevents light or projection passthrough?
