@Koboo I also got these issues during testing, but the mappings (especially the IDs of the materials) for the different versions should be correct. It's kind of weird..

[terrarier2111]

The models just can't be loaded, because of differing names from materials/textures

[terrarier2111]

But that's a different issue

[Koboo]

Sry, I didn't know that. But very good work. My appreciation goes to the whole team behind Leafish! Keep up! 👍

The ids here are wrong, please recheck them
