As a note to anyone who wants to contribute wrb8 files, do know that there are trash data that seems to occur inconsistently in those files, and their purpose, nor where they come from, are not understood at this time. So if you do wanna share them, do so at your own risk.
Alternatively OP can wait for a WB8 -> WRB8 update to be finalized in the plugin.
Also, as a final word: wrb8 doesn't affect ones gameplay in any way. They are purely cosmetic. Just thought I should point this out.
Cheers all.
