I know i can delete the textures not used but as said, it saves ALL the textures which is ALOT to delete PER model, alot of tedious work, so i just wanted to know if there would be performance problems if a model has so many skins [external] but only uses 1/2;

While writing this i thought of a solution, i could delete every other model in the map before exporting the new group, the undoing the deletion after export, i guess i'll try that, but i would still like to know:

Is there would be performance problem if a model has so many skins [external] but only uses 1/2 ?

and yes i know of the MED method, wont help much here since the groupings are unique to places in the map;
