The wonderful model that will be used in the examples for this release was made by Psionic (http://www.psionic3d.co.uk), and he was kind enough to let me use it. This is the beta build. That means it has all the functionality I plan on adding, and all that separates it from the final release is the test of time.
The MeshSplitter.cs file, in case your wondering, splits the meshes in a model up to account for a maximum number of bones in a matrix palette. It works, but is not optimized.
To use it, add the source to your project and in your model processor, add this code before you do any processing:
ModelSplitter splitter = new ModelSplitter(input, 50);
bool neededSplitting = splitter.Split();
Split returns true if any meshes in the model needed to be split up.
Not all the tutorials will work until they are updated.
