Hi so I loaded both dawnguard and herhtfire to see some models etc but whne I load for example one of the castles I see a lot of Red Markers that show missing models any idea why?

I case someone is going to answer this...

SInvalidationFile2 with all dawnguard and the others bsas don't work .

Could you post the archive part of your .ini? Although, that shouldn't really stop the models loading in-game...

To load I had to extract them wich is stpid habing a bsa ...

That's really weird, but at least you got it working!
