Hey, In new here and just started using Hammer yesterday.
I just needed to edit change some textures with a machinima in working on and I've been going mad trying to figure out how to fix all these leaks and compiler errors popping up.
Considering I've just been taking official maps straight from the game their shouldn't be problems should there?
Has anyone else had similar problems?

How did you get these maps? Decompiling? Or are you talking about the sample VMFs provided with the SDK?

the map I want to use is sp_a1_intro 3, where you first get a portal gun surrounded by ratman paintings.
I got it by decompiling it myself, I also had a pack of in official maps ready decompiled that someone on another forum put up. Can't get either to work.

No official map has a leak. They are sometimes not perfect built, but have never leaks.
It's not unusual that decompiled maps have leaks. Just use decompiling for understanding special mechanincs of the game, not for copy and paste things!

Sometimes because Valve uses instances it decompiles a bit wrong (as it inserts an angles keyvalue). However it shouldn't mess up any world brushes (the brushes that are meant to seal your map). The only thing I can think of is that an entity has somehow rotated from an instance into the void. Try hiding everything except world geometry and see if it leaks then.

If that isn't the problem, check the point-file to see where it points to. And you should be using BSPsource as it is a lot better than VMEX for decompiling.

This. BSPsource has a "Fix rotations" option also.

True decompiling sometimes leaves stuff out
