Next break the link to the original prefab by creating a new one to link to - In your Prefab folder in the project window, create a new empty prefab from the menu Assets[Menu]->Create->Prefab and name it something different. Your game runs faster when using the model with just one GameObject, because the model contains fewer triangles and so it renders faster than the robot that has many small parts.

How can you make a prefab that can expand to show its constituent objects? Models must be re-exported manually if changes are made to the original file. We can use prefabs and raycasting to solve this, but I think it is more efficient to modify the textures of the walls, i.e., to add small texture paches (including albedo and normal maps) onto points of impact. And this is the properties of the model: Then in the code I did the following: Mesh mesh = HexPrefab.GetComponentsInChildren<MeshFilter> () [0].sharedMesh; And now I can get the dimensions of the mesh like this: mesh.bounds.size. If material generation is disabled (i.e. RipperStore Official. When modifying a material, it affects all objects and prefabs that reference that material.

You can nest Prefabs inside other Prefabs to create complex hierarchies of objects that are easy to edit at multiple levels. This way allows me to script everything based on a small amount of metadata. Note that the user's problem (six years ago) was due to trying to change a texture on the material, not trying to change which materials are referenced by its renderer as you describe here. "GameObject/Break Prefab Instance Completely", "This is dangerous and can lead to broken objects and broken links to this object because it will be destroyed and recreated. If you had any overrides on your Prefab instance before you unpacked it, those will be baked onto the resulting GameObjects. Is "I didn't think it was serious" usually a good defence against "duty to rescue"?
