Whenever I try to add an instance, the portal file won't open.

It must have to do with the entity, because I can take a (somewhat longer) detour and copy the instance directly from the file.

P.S.S in the the sound browser in hammer

P.S.S.S Good luck

FINAL THOUGHT Have you tried saving and reopening the map?

P.S FINAL THOUGHT copying an instances into a map still makes it functional, but very complicated to modify (like elevator transitions)

P.S.S FINAL THOUGHT instances are easier, hopes this helps

I'm putting the instance in a saved map, in the right place. It just won't read the .prt file when compiling.

When the compiler won't read my .prt file, because of a leak, if you see yellow or red, that means there's a problem

Try compiling without vvis

Also, make sure the map is saved under "portal2/SDKcontent/maps", or else the instance won't load. I had this problem when I started Portal 2 mapping.

This.

Also you have to save the map before any instances show up. I noticed this when I wanted to place an instance when I clicked 'new'.

Is there a leak in the instance?

I would be surpried, they're the offical set.

Will try.

EDIT: Works, for you! Although, isn't vvis an important part of the compilation?

Which instance are you using?

Monitors, gameplay, etc.

Fixed now
