The First Descendant

[L2Fanatic]

...
Judging from your error you're not using the correct game detection, you need to select "The First Descendant" not "UE5.2"

The option was under "Unreal Engine 4" engine version.  
What a rabbit hole.  

Thank you Ehlyon.

@Junsoo: If you don't know how to do such thing in umodel, maybe it's not possible - for example when different mesh parts or accessories are not using the same skeleton/bones. Also, even you'll combine what can be combined, it would be for preview only and export will be separate meshes anyway. Like it was already said above, it's better to export required assets and work with them in editors like blender, which provides a lot more options.

@Hotaru: Surely not with umodel. You can take a look at recommended tutorial from tutorials section and this topic with current limitations to get basic idea what you can do with it and what can't.

@YWYOVO: This crash should be fixed now in the updated build. Also make sure you have latest specific build before reporting issues, because according to the error message you're using quite outdated build (though in this case the issue was still present there before the update). Latest build is always available in the topic, mentioned in the first post.

As for the textures, it was already explained above - the game is using virtual textures, which are currently not supported by umodel. It's highly recommended to read topic with current limitations and other possible issues, mentioned above and in the first post. You may also read the rest of this topic, it has some useful info on previous pages.

@Icey: Morph targets are not supported at the moment in the specific build (except for a few games on earlier UE5 versions with old format), which is explained in the topic with general limitations, mentioned in the first post. Please read it carefully before reporting other possible issues. Also this option is disabled by default in the specific build, not sure why you've decided to enable it.

@zangchunyu: It should be fixed now in the updated build. If you have other crashes for this game, please report them as well.
