I have been following your tutorial and the farthest I have gotten was making the options for scaling the mesh. The reason being when I did was because after debugging my mod or running it in Jackhammer, half-life crashes and I get either an "ntwdll" / "access to xxxxx.dll is denied". I spent weeks trying to get this to work but to no avail. I repeated the tutorial a second time and took a break for a couple weeks, stopping before the part where you program the different methods of collision and the error showed up again. Keep in mind, this only happens when I have my static mesh in the map. This is what shows up on the end of the output when I debug half-life: "
Wrote erroneous message to buffer.dat
