In the previous recipes, we have been working entirely with hard shadows. The Sun in our 3D world can produce these hard shadows, and they are called by this name because they have strong and well-defined edges with less transition between illumination and the shadow. Soft shadows can be produced by the Sun in certain circumstances, and the sky, likewise, can create these diffused shadows with soft edges. Let's see how we can apply soft shadows to our project and how they can enrich the final look.
Before you start, you need to have some 3D models in your project to see the effect; make sure that these are at least of medium quality so that you can see the shadows. In any case, you can use one of the examples available in the Examples tab to see how soft shadows can boost an image or movie.
