-opVisualizer implements an asset loading mechanism that allows you to add your own 3D resources as external files to the application without code adaption. The 3D models must be wrapped in a *Prefab* and compiled into a catalog, that you can distribute along with the opVisualizer. For more information, please see the development guide [here](https://www.eclipse.org/simopenpass/content/html/index.html).
