UE 5.3/5.4 can also drag & drop as-is (.gltf, .glb files only)
Check the “Combine Static Meshe” checkbox in the “Static Mesh” section when importing.
If the “Are you sure you want to override asset Message” dialog box pops up frequently during import, hold down the ESC key (there may be another solution).
Do not use the OARSelectMaterial plugin, as it does not work properly.
Collider is set manually at import (the beginning of the file name is UCP_: with collider, UNC_: without collider)
When importing glTF/glb files with skeleton information, UE5 does not follow the glTF2.0 standard (*). In this case, OARConverter outputs a glTF/glb file that does not conform to the glTF2.0 standard in order to ensure that UE5 reads the data.
(*) In glTF 2.0, matrix property is not required or should be ignored if skin property exists in node data, but in UE5, matrix property is required (depending on model structure) even if skin property exists.
If you want to get the same general glTF/glb files with skeleton information, please output those for Unirty.
