For third-party 3D models already in FBX format, we can just import them directly into our Unity project. For models in other formats, if we have the same application that we used to create the model, then we can do what we did in this recipe; that is, we can open the model in the modeling application, remove any unwanted elements, and then export it in FBX format.
3D modeling applications are complex, sophisticated applications. However, as demonstrated in this recipe, all we really need to know is how to view, select, and delete elements, as well as how to export the model in FBX format.
In this recipe, we removed the unwanted elements of the model in the Blender application. It is also possible to remove some elements after a model has been imported into Unity – some elements will appear as child GameObjects when the model has been added to a scene.
Different modeling applications work at different scales, so Unity has made it easy for...
