[Help] Level Editing in Hammer: areaportals & leaks

Hi, im posting here as a last resort, i'v looked into many tutorials and spent a lot of time reading the wikias and working on my level BUT, areaportals are giving me such a hard time. So here it goes:

Im working on a map called "docks" for insurgency which features a big outside area that is really heavy in terms of performance.

So im playing around with hint&skip, occluders and areaportals. When it comes to areaportals, i can't seem to implement them without having leak errors in the compile process. It tells me which brushes are the problem, but in the editor, everything seems fine.

So my question is:

Displacements going through areaportals cause leaks?
Invisible textures such as nodraw, ladder, playerclip, skip/hint, cause leaks? (as in z-fighting with the invisible brushes or even going through the areaportal)
What about props? do they cause leaks when going trough area portas?
Im currently not at home, but i will update this post with screenshots of said problem and upload a simple .vmf to show the problem.

Thank you so much for your time&help.

Cheers

Your videos are unavailable, I can't see them.

As for area portals, they ignore everything except non-entity brushes with opaque textures and water.

An area portal leak occurs when one areaportal side can find a path to its own other side. So area portals are used to cut the map up into closed off sectors.

If you are having issues sizeing them correctly, turn off all displacements, props and entities in the vis group thing first (besides other area portals).

Hint/skip/ladder/playerclip textures are ignored by area-portals completely.

Nodraw is considered an opaque texture by the engine, so if it is on a non-entity brush, it can be used to seal an areaportal sector.

Water is strange, you can't have the water surface cross through an area portal. You must stack 2 area portals, one below the water, and one above.

In short, the same rules for sealing your map from the void apply to sealing area portal sectors from eachother.

Thanks for the reply, sorry about the videos, i uploaded them to vimeo, should be working now.

can u give me an example of a "non-entity brush with opaque texture"?

thanks in advance.
