Im going insane here!
I've been working on a map for a few days now and I just tested it with light and vvis for the first time(kinda). And I have this problem I cant solve. I have some vactubes with cubes in them that work perfectly without vvis, but when I compile with vvis they cannot be seen UNLESS THEY SHOULDNT BE SEEN! its like it has reversed itself. I have 2 of the same pipe, one pipe starts "inside" the map and the cubes cannot be seen, the other pipe starts "outside" of the map(on the other side of a wall) and can be seen inside the map but not on the outside.
It looks like they work fine if they have no animation.
What the hell should I do???

Update!
Ok, it looks like when they have an animation vvis thinks its outside of the map when its not(or that the player cant see them when they can). Can I tell vvis to ignore that or something? Can I tell it to always draw them or something?

Looks like something wrong with your leafs. Read this page and take note of when they mention func_viscluster.
