ENG. The Unreal Material Importer is a free plug-in for Unreal Engine 4 that you can use to load MODO material .xml files and apply them to 3D meshes of a game level in the Unreal Engine 4 editor.

If you have a MODO scene, you can export 3D meshes in the form of .fbx files, and materials and textures as .xml files.

You can then apply the exported materials to the .fbx 3D meshes in Unreal Engine, using the Unreal Material Importer plug-in.
