@spiritovod Thanks again, i managed to export without crashing by doing this :
I've added support for this game. I have just a few files with skeletal meshes and textures, no skeletons, no animations, no statics. So it would be really nice if someone could test all assets.
To make things working, you should specify -game=ngb or select this game from UE4 list in UI.
I didn't add the game to compatibility table or readme yet, I need test results.
Iwas able to export everything in gltf with this settings :
I didn't find a way to make it so Unreal correctly import the material, i have to manually drag the textures in the material in Unreal.
Also the only way i found to export the animation in the gltf is to use " Find animations" in Umodel and then export from there one at a time.
If anyone was able to put extract other elements from the game, please share.
