When you enable Generate Colliders on the Model tab, Unity automatically adds a Mesh collider when you add the Mesh to the Scene so that the physics system considers it solid. Mesh Colliders are components that use imported Mesh data and Unity can use them for environment collision A collision occurs when the physics engine detects that the colliders of two GameObjects make contact or overlap, when at least one has a rigidbody component and is in motion. See in Glossary: Mesh Colliders A free-form collider component which accepts a mesh reference to define its collision surface shape. A collider doesn’t need to be exactly the same shape as the object’s mesh - a rough approximation is often more efficient and indistinguishable in gameplay. Unity uses two main types of colliders An invisible shape that is used to handle physical collisions for an object. If Unity doesn’t find a matching Material, it generates a new Material. In each Scene, you place your environments, obstacles, and decorations, essentially designing and building your game in pieces. Think of each unique Scene file as a unique level.
Although slightly slower, the main disadvantage of the exhaustive search is that there could be two or more Textures in the Project with the same name. If this fails, Unity performs an exhaustive search of all Textures in the Project. First, the importer looks for a sub-folder called Textures within the same folder as the Mesh or in any parent folder. Unity follows a specific search plan to automatically look for the Textures used by a Mesh on import. Unity supports triangulated or quadrangulated polygon Meshes, so you must convert Nurbs, Nurms, and Subdiv surfaces to polygons.
And Unity has great interactivity with most 3D modeling software. See in Glossary Deformer, UModeler, and Mesh Editor. Nurbs, Nurms, Subdiv surfaces must be converted to polygons. Unity supports triangulated or Quadrangulated polygon meshes. Meshes make up a large part of your 3D worlds. See in Glossary modeling plugins, such as Mesh The main graphics primitive of Unity. Offers a wide variety of assets, from textures, models and animations to whole Project examples, tutorials and Editor extensions.
