Make the change in the whitelist so that:
// // By default, when in pure server mode, most content file types are only allowed to come from Steam. // materials\... from_steam models\... from_steam sound\... from_steam // // Allow custom player models. Don't do CRC checks on them because the clients may all // have different custom models and the server won't have them all. // materials\models\player\... allow_from_disk materials\models\weapons\... allow_from_disk models\weapons\... allow_from_disk models\players\... allow_from_disk
Congrats, custom player and weapon skins now work again.
