[.net] ModelProcessor

When you write a custom processor like that, you'll want to do so in a separate library. When you compile said library, then you can add a reference to that library in your game's "content pipeline assemblies" section in the project properties.

Well, the documentation can say it better than I ... here is a quote from the doc, "How to: Add a New Processor or Importer to XNA Game Studio Express":

Quote:

The following procedures add a custom importer and processor to an existing game solution (called "MyGame"). It is assumed that the new importer or processor was copied to a local sub-directory of the "Mygame" solution. To add a custom importer: -Open XNA Game Studio Express. -Load the MyGame solution. -From Solution Explorer, double-click the Properties node. This opens the Properties window for your current project. -Select the XNA Content Pipeline Assemblies tab. -Click the Add... button. -Navigate to the directory containing the custom importer. -Select the custom importer and click Open. -Save the solution. The new importer appears as one of the choices when selecting an importer for a game asset. Use this same procedure for adding a custom processor.
