Starting with Three.js, I have created a scene where a marker points to the surface of an object. For a better comprehension of where the marker is pointing to, I wanted to add some shadows. I have set a shadowmap with a texture of 2048. But still the shadows are very very blocky, and this is hardly acceptable for my visuals. Is there a way to improve this somehow, or use another kind of shadow process if any?
Thank you for your help.
