rf folder -> item -> modelitem -> mesh/tex
delete files from mesh and tex folders that u dont want to see (best make a back up just incase)
and this will delete it so u cant see those items on the ground for any reason (player drops and normal so not just PB) - u will still loot those items if u press 'space'
u should be able to work it out from the names which is which but feel free to ask if u need anything else
