Because it's SUPPOSED to do that when you don't tell it what to compile.

And how am I supposed to tell it what to compile? I'm new to this, I had no idea that making simple models required so much stuff to do. What do I do?

C:\Program Files (x86)\Steam\steamapps\Team Fortress 2\bin\studiomdl.exe

But it opens for a fraction of a second then closes... Why does valve have to make these thing so hard to do? God dammit.

Awesome, found it thanks!

If you can't find it, you haven't installed Team Fortress 2, because it's included with it.

Pretty sure I did actually install tf2, I just don't know where to find it.

StudioMDL.

Umm isn't it the same as GUIStudioMDL? Because I can't even find the one you're talking about.

引用自 Vintage：

Firstly, don't use outdated tools (GUIStudioMDL is an example). Secondly, use Team Fortress 2's compiler for the best results (seeing as Garry's Mod fully supports Team Fortress 2-compiled models, Team Fortress 2 compiles DirectX 7<, 8, and 9> models, and Team Fortress 2 is free).

Umm ok, what tf2 compiler can I use?

I don't have neither Half life 1 ep 1 nor orange box. Does that mean I can't make any models for gmod? Because that would be pretty lame honestly.

What do I use to compile them?

I probably sound like an idiot.
I tried exporting in SMD because I remember pretty well that's what GMod used. It didn't work, I also tried in SFM but there was no other model with .smd format.

In the Scene properties (the third icon in the icon list) on the right.

Thank you ! :D
