Mods for retail HL2 in the beta?

[valver007]

Is it possible to use mods that you can download and use for half-life 2, retail specifically (from websites such as GameBanana https://gamebanana.com/games/9) in the beta engine?

Models from retail version of HL2 won't work in HL2 beta because they have different .mdl format. Same goes for maps. So no, these won't work.

yeah eesh, both of these are wrong, there are programs out there that convert models retail source weapons to beta source, which is how custom models and weapons in Team GabeN's mods were made, and also you can literally convert maps from retail to beta using bspsrc
