Unity is the ultimate game development platform. You can bring a lot of detail to your GameObjects by using precomputed textures to provide normal mapping and ambient occlusion. I know how to do projective texture mapping, but in the implementations I've seen, the projected texture is passed as an additional texture to a shader - so it's basically multitexturing. It can be used to implement blob or projected shadows. These nodes allow you to reference images in your Unity project to bring them into the Shader you’re creating.
