Currently only the importers work.

Unity: Unity 6 (6000.0.32f1)

1. Clone the project
2. Open via Unity
3. Rename the objects (because I can't register ".obj" importer due to Unity limitations and their native importer shit)
4. Drag and drop the objects onto Unity editor. Voila!

Currently supported objects:

1. Worldmap Texl (rename as .texl extension)
2. Worldmap wmx (rename as .wmx extension)
3. Battle stages .x (no need to rename)

See attached samples in SampleAssets - there are original, renamed files
