In Half-Life, each player can set their desired player model (for example: model "zombie"). In doing so, they can specify any string for the model (model "abc"), and only those players who have that particular model ("models/player/abc/abc.mdl") present in their game client will see it. All others will see the default "gordon" model.
My question:
Can I add an entity on the map with studiomdl with the same logic?
