[brN17]

not exactly, It's different since It's exclusive for SH Mod and not as complete as yours are
please tell me If "entity_set_string(id, EV_SZ_weaponmodel, g_ModelPData[iModelIndex][PModels]);" is correct too, I want it to save on nvault as well

complete code not fully tested since it's crashing:
