With this PR it's possible to add a collision during the Mesh import, directly in editor. To generate the shape is possible to chose between the following options: - Decompose Convex: The Mesh is decomposed in one or many Convex Shapes (Using the VHACD library). - Simple Convex: Is generated a convex shape that enclose the entire mesh. - Trimesh: Generate a trimesh shape using the Mesh faces. - Box: Add a primitive box shape, where you can tweak the `size`, `position`, `rotation`. - Sphere: Add a primitive sphere shape, where you can tweak the `radius`, `position`, `rotation`. - Cylinder: Add a primitive cylinder shape, where you can tweak the `height`, `radius`, `position`, `rotation`. - Capsule: Add a primitive capsule shape, where you can tweak the `height`, `radius`, `position`, `rotation`. It's also possible to chose the generated body, so you can create: - Rigid Body - Static Body - Area
