I understood that, yes. It does not change the fact that you need to ensure that the material and the texture of the mesh are getting loaded before. You don't need to import them since they are already present. You only need to ensure that the loading order is correct.
A static mesh is basically everything which is not rigged, with "rigged" being basically synonym for "skinned". You can see that a mesh is rigged/skinned in OpenBRF if it is possible to play an animation for it.
You don't need to export/import things from one brf to another. You can simply copy paste across brf files.
And you have still not reported it the cloak looks alright in-battle
