ERROR: Uknown Model Option VCAFILE

OK according to Valve Software’s Developer Wiki, one of the options for the $model command is vcafile. When I try to compile the QC through the Blender Source Tools addon, I keep getting this error in the console window.

Here is my QC file as it is right now:

If vcafile is a valid option for the $model command, why is it coming up as an unknown?

What kind of compiler does the blender addon use? Tested it with the dota or sfm one specifically?

It seems it’s exclusive for Dota 2 / SFM, so you should try compiling using their studiomdl.exe
