Mesh and animation files
Finally, let's cover mesh and animation files. These file types are essentially large arrays of vertex and skinned bone data, and there are a variety of techniques we can apply to minimize file size, while keeping a similar, if not identical, appearance. There are also sometimes ways to lower the cost of rendering large groups of these objects through batching techniques. Let's look into a series of performance-enhancing techniques we can apply to such files.
Reducing polygon count
This is the most obvious way to gain performance, but we should never disregard it. In fact, since we cannot batch objects using Skinned Mesh Renderers, it's one of the only good ways of reducing CPU and GPU runtime overhead for animated objects. ...
