It's really simple: Shadows won't be cast. I checked the light source to cast shadows, but they aren't cast.
I want a text to cast shadows. I want to place the text on a surface within some video footage.
I already traced the camera motion with tracking and managed to align the text with the markers placed on that surface.
I also don't know how to make the shadow cast appear but not the surface.
I animate the text in the 3D-view and then place the animated scene over the footage over as a strip in the Video Sequence Editor.
Yes there is a surface to catch the shadow, Yes there is a light source.
I tried following some tutorials, but they either have some weird options in them that my blender version doesn't (2.76) or their objects just cast shadows by themselves by default.
