Exported models from L4D2, where are the textures?

Hi there people, I spent my day searching on the internet how to export models from L4D2 to 3Ds Max (I want to make a fan-art with the characters), now I have them in 3Ds Max, with their bones, so that’s great, but I don’t have the textures. I’ve got some vtx files, also a vta… I don’t know if it’s that.
Does someone know how to get the textures from L4D2 models please?
Thanks in advance.

Use GCFScape and VTFEdit to extract the textures from the L4D2 pak01_dir.pak file and VTF edit to convert the textures to TGA; or you could get a VTF plugin for 3DS Max.

Thank youuuuu! It works, finally!
