Hey Heljumper, have you had any success recompiling using your old technique using Steampipe? Let me explain a little further.

I'm grabbing the mdl (then converting to smd) and qc data from the zipped workshop items after I verify and trying to replace an existing hat ingame (ex. when you used the ushanka to be replaced with the blender hat in your old tutorial). I am able to get everything running in GUIStudio but the hat isn't being replaced.

I feel like the old process should still work, is there something I'm missing here?
