Prepar3D v4 MDL support

In my previous post about Prepar3D v4 support of my tools I mentioned that the MDL format didn’t seem to contain many changes. On further investigation it turned out that there are a number of changes and new sections in the MDL format. These are related to the following new functionalities:

  • Support for a second set of UV coordinates, including the material attributes to specify which texture uses which set.
  • New material attributes, mainly for the detail map and heatmap.
  • Support for material scripts.

The development release has been updated to be able to write all these new features as well. In the material editor you will find a Prepar3D v4 specific section with all attributes that are only for Prepar3D v4.

Given these changes, you will find the Prepar3D v4 MDL and Prepar3D v4 BGL as a specific export format in the save dialogue now. In the options you will also have to set the path to the Prepar3D v4 XtoMdl and Bglcomp. If your SDK is installed correctly these tools should be detected automatically by the way.

    Does this mean the scenery I built in pre V4 will not work and I have to recompile bgl and models or it will work sans bulleted features?

      No, older bgl files still work due to the backwards compatibility. Only when you want to use the new material features you need to recompile.
