Use Crowbar to decompile the mdl, which you can download here: http://steamcommunity.com/groups/CrowbarTool

That’ll turn the MDL + vtx’s into SMDs.

Download the SMD import/exporter for your version of 3DS Max and that’ll let you import the model.

Then to decompile the VTFs into TGAs use VTFEdit, which you can download here: http://nemesis.thewavelength.net/index.php?c=238
then you can use the TGAs for your material.

VTFs are textures – they contain image data. VMTs are materials – they contain plaintext parameters for the specified $basetexture. VTXs contain vertex data for models. You can import VTFs into 3ds Max by converting them into PNGs/TGAs with VTFEdit and importing them from there. You cannot import VTX files alone as they are only part of a whole model, but you can use Crowbar to decompile models for importing.

Basically:

VTF: Texture images
VMT: Texture parameters
VTX: parts of a whole model

you can use crowbar to get the .vtx files

Thank all of you people:)
