How do I decompile models for use in Blender?
I want to do some editing to some of the game models, and Blender is my 3d editor of choice. I'm willing to use a different one if need be, but that's not the point here.
The Valve MDL files seem to be a compiled version of SMD files, from what google has told me. The only way I've seen to reverse this procedure is to use MDLDecompiler. However, the folder it needs to be placed in does not exist on my system. How can I make the program work? If nothing else, would it be possible for someone who has that folder to run the program and send me the files? I'm trying to get the models for the personality cores.
Check this tutorial. When you have the .SMD files you can open them in Blender using the Blender SDK Tools

[/spoiler]Right, but as I said, I don't have the folder that the decompiler needs. The /NAME/sourcesdk folder. I don't have that.
Yeah, I thought that might be the problem. I did download the SDK when I saw that the folder didn't exist, but it's still not there in the folder. I do not have the /sourcesdk/ folder.
Yeah, I have. Inside the NAME folder I only have portal and team fortress 2. Those are the 2 folders.
Did you download the SourceSDK tools or the Portal2 Authoring Tools? because you need the first ones, and when you start them, they should create the required 'sourcesdk' folder:
Hmmmm... or will this issue have to do with the steampipe?

[/spoiler]I already had the portal 2 authoring tools and I just now downloaded the Source SDK.
Okay, so I found a SourceSDK folder in the Steam/SteamApps/common, not in the Steam/SteamApps/NAME. But I still don't have Steam/SteamApps/NAME.
