Super Raycast unity asset allows you to do high-quality raycasting for renderers without the need for collision mashes, colliders setup and more. It also contains animated skinned Mesh Renderers for the projects.

To get higher-quality normals you need to use bump maps. On the other hand, if you want to get higher-quality hit points you also need to have high maps. Download more packs HERE.
