Hl2 modeling is a pain in the ass. There are varying degrees of irritation to most every plugin that is out for every modeling program that I have used from maya to 3ds and so on. The main irritation is that they are just way too complex, ergo making a model come to fruition is more than a sum of its parts. In an effort to make things work, and work they do, I have taken the plugin out of the mix, and I give you my very own OBJ to SMD Converter. The app is below, you should have no issues running it, and if you do, let me know and ill do my best to fix her up. some basic documentation is included and i also attached the source. Feel free to distribute it as you wish, i am an open source friend.
The reason i made this application is because all modeling programs today output their content in .obj format. You don’t need to learn their scripting language or anything of the like. Just drop it on here and poof, SMD created.
Another revision of this app, enjoy. Should be a little faster now.
