[Questions]Advanced hammer Usage.
1.How to make water move?I tried to make the brush of water a func_door but ingame the water didn't show up.Also I tried to parent it with another func_door.But I don't know which entity I should tie the water to.If a func_brush,same thing happens.Any good idea for this?
(In addition, I'm not sure if I need to tie the brush of water to func_water or something like that even I want it static.)
2.How to put half-life 2 materials to portal 2 maps?In the Portal 2 authoring tool , I add a half-life2.fgd from portal 2/bin but seems it's not enough.
1) The only way to have moving water is a func_water_analog brush with the P1 goo texture.
2) FGDs don't contain any information about materials and so forth. You need the files from the GCF. Look at the "content porter" tool on ModDB, it's useful here.
How do I get the Content Porter to work properly? I've followed everything in the Readme file, but when I run it, I get some red messages and I can't even read them, and nothing happens at all. I've also tried to follow josepezdj's tip here, but I didn't find any "source engine.gcf" file
Yea gcf files are non-existent after the steam pipe update.

Textures in HL2 now are inside your "common/Half-Life 2/hl2/hl2_textures_dir.VPK" and "common/Half-Life 2/hl2/hl2_misc_dir.VPK" files. Use GTFScape to open this kind of files. You won't really need to do anything to those textures except to extract them in a folder called the same as inside the VPK; you should simply keep the folders structure inside portal2/materials, ok?
For example, if you want the file "/brick/brickwall001a.vtf" (this one from "hl2_textures_dir.VPK") and "/brick/brickwall001a.vmt" (this one from "hl2_misc_dir.VPK"), you'll need to create a local folder "portal2/materials/brick" and then extract those 2 files to the newly created folder (you can simply drag the files from the opened VPK file in GTFScape to your local folder).

Well I've checked the func_water_analog on developer.valvesoftware.com but seems I don't have the right texture for water.So whenever I tied the water to this entity,there was no water from the very beginning.Is there a workaround for this?
ah that's a really smart workaround ! thanks 
For example, if you want the file "/brick/brickwall001a.vtf" (this one from "hl2_textures_dir.VPK") and "/brick/brickwall001a.vmt" (this one from "hl2_misc_dir.VPK"), you'll need to create a local folder "portal2/materials/brick" and then extract those 2 files to the newly created folder (you can simply drag the files from the opened VPK file in GTFScape to your local folder).
It's a bit complicated now...I got 2 hammers available.1 is P2 Authoring Tool and another is from Source Film maker.The hammer from SFM is well prepared for HL2 (maybe,because I see HL2 textures.The fgd is base.fgd).Which should I choose now?I want to make Portal 2 levels with some HL2 decoration.I've searched on google and find people say that I should find the .gcf file but I can't find any .gcf file from /steamapps as they say.I got the GCFScape but don't know how it work.Could you give me some tips?I'd be grateful.
There should be gcf files in your steam/steamapps folder if you installed hl2.
Then there's content in steam/steamapps/common/half-life2/hl2/ there should be vpks in there (also open with GCFScape)
and finally if you're using sfm the content is also in steam/steamapps/common/sourcefilmmaker/game/hl2
Hope that helps
