I compiled that with HL2 one because the Garry’s Mod one doesn’t work. I tried checking all the directories but the problem seems to be with the meshes that I separate. If I delete from the .qc *$body Track5 “track_RShape_split_2.smd”* and *$body Turret2 “Turret_02.smd”* Crowbar compiles the model without problems, but as you see the turret and the track are messed up.

**EDIT:** I tried even with .dmx and TF2 compiler ('cause I don’t have SFM): same error.

**EDIT 2:** I separated the turret in 5 different .smd files, edited the .qc many times, making everything from start and the result is always the same.

I’m not really an expert about this, but if someone needs that here’s the compile log I always get when compiling:
