I don't think you need the extra brackets for the $bodygroup section.

I think this is all you need:

$bodygroup Eyes
{
studio "Happy.smd"
studio "Angry.smd"
studio "Hurt.smd"
studio "Half.smd"
studio "Closed.smd"
}

What's with the quotes at the end? I don't think they should be there.

"Line 34 is incomplete"

What is line 34 of your QC file?

This doesn't seem to be just a bodygroup limit. It seems to be a mesh limit. If you take one of the bodygroup SMDs and try to build it with $body (not desired behavior I know), it still does not build properly.

The "blank" in the bodygroups also contributes to this limit as Momo pointed out. Counting them all up, it seems to be a maximum of 32.

Unless there's some way to work around this limit that I'm unaware of, you have a few options in this situation, but they probably aren't going to help you.

1: You can remove one of the "blank" slots, however this is probably not desired. I assume this is some form of cosmetic and you'd want the "blank" slot for showing nothing.

2: You could merge 2 or more SMDs together. This is probably not applicable here, as you probably want all of them to be separate. (Though I don't know what you want to do with this model, so maybe this is the best solution)

3: Get rid of one of the bodygroup SMD files that you don't really want.

GitHub is indeed great. Though merging can sometimes be among the biggest of pains out there.

Oh, my bad! I didn't notice that.

This is really just cosmetic, but it could be very useful. That would be splitting up the QC into multiple files with the .qci extension. For something like weightlists this would be great.

Instead of having one giant QC file that 50,000+ lines long, splitting it into multiple files would benefit readability.
