Sorry for the late reply.
that's odd... I have no idea atm.
It should be standard in SFM.
kinda odd that you don't have it.
Try validating the game cache to see if that will help.
well i dont have sfm i just need the .mdl and the texs and materials for blender cause u use a mdl importer tool
Really?
Since SFM is free to download and all the TF2 content is already there.
You should be able to extract plenty of resources from it.
