I've been trying to do this with tfc without using the tfc module because tfc_setmodel is the only function i use from it.
afaik entity_set_string EV_SZ_model just doesnt work for players
DispatchKeyValue(id,"replacement_model","Aqua fresh"); works in tfc but you have to respawn for it to take effect. How would i make it take effect immediately?
but i think replacement_model is a tfc specific function from item_tfgoal Is there an entity in DOD that allows you to change the playermodel
