If you need to set up your objects further in Unity (adding physics, scripts or other coolness), save yourself a world of pain and name your objects properly in your 3D application. That is, the values will stay the same, but will no longer have status as overrides, since theres no Prefab to override. Big files can slow down Unity project imports or Asset re-imports, because you have to run the DCC software you use as a background process when you import the model into Unity. You can also create variants of Prefabs which allow you to group a set of overrides together into a meaningful variation of a Prefab. For GameObject type variables, you can assign any GameObject to the variable, and the Instantiate function returns a reference to the new GameObject instance. If a mesh does not have vertex colors, Unity will automatically add an array of all-white vertex colors to the mesh the first time it is rendered. The prefab acts as a template from which you can create new object instances in the scene. The following script (placed on the projectile Prefab) performs the action of instantiating the explosion at the projectiles current position and removing the projectile GameObject when the projectile collides with something.

When you enable Generate Colliders in the Import Settings, a Mesh collider is automatically added when the mesh is added to the Scene. Unity supports triangulated or Quadrangulated polygon meshes. If it is enabled then it will do the following: Unity uses two main types of colliders: Mesh Colliders and Primitive Colliders. (Ep.
