  • How to associate material info with a ModelMeshPart?

    Last post by SorcererXIII
      • So each set of polys in a Model with a common material becomes a ModelMeshPart once you load it into the game. What I can't figure out is how you determine which material got associated with which ModelMeshPart. There don't seem to be any public members of ModelMeshPart that tell you the name of that part, or any way to somehow implant your own "blind" data (to use Maya's terminology) an

      • Hi! I'm just in the process of writing a proper text rendering component for XNA. It fully integrates into the content pipeline and can import any TrueType font during compile time. Just like any other XNA framework content, an .xnb file is generated from the font which can at runtime be loaded by XNA's ContentManager, eg.
