This should be a breeze with a locked tripod shot. And you don’t even need C4D to do it. I would put the shot in After Effects, create your text, make it a 3D layer. Then rotate and scale as needed, and maybe play with some overlay modes or slight masking (cracks, grunge) to make it look more real.
Also, don’t make the letters pure white. Try to make them match the white balance of the scene. Hope this helps, and good luck!
