I've tried it myself and it normally works
In the something.lua file I have these 2 lines:
removeBasicDefaultModels()
addModel("combine", "male", "hunters")

The problem must surely be due to the localization of the something.lua file
Make sure the file is in garrysmod/lua/ultimateph/models/

And if you're using the addon on a dedicated server, the file should be in the server folder, otherwise in your game folder.

alright I'll check, thanks for the quick reply!

Alright it works, probably just had a singular typo. Final questio, does the default removal line replace the playermodels with the ones selected from the player in other modes?

Change of mind, everytime I respawn the whole game bricks and I need to restart the whole machine to like do anything.

To answer your question (if I've understood it correctly): no.

And for crashes, you need at least one playermodel for each team, otherwise the game can crash when you change teams.

Salut j'ai une question ! je ne comprend pas comment ajouter les models dans le jeu. Ou se trouve le "name" du model que l'on souhiate ajouter ? J'ai trouver des models de perso TF2 sur le Workshop que je souhaiterais mettre à la place du Hunter mais je ne comprend pas...

je pourrais avoir de l'aide ?

Pour trouver le "name" du model, tu vas en sandbox et dans le menu de sélection des models joueur, tu laisse ta souris sur le model et le nom devrais s'afficher en jaune
