Seeing as the manifest tools are almost totally undocumented, getting it to work is an absolute pain in the neck.
I managed to get func_instance entities to work perfectly, but the .vmm is totally ignored by VBSP. I'm beginning to think the features are in hammer, but not in VBSP (July 7th vbsp anyway)
Here are the files I've been experimenting with, in my attempts to get this to work
If you have any better luck, post back and share what you did!
