I've got this idea to make an UT3 map in the Aperture Enrichment Centre.
But I need the Portal textures in normal formats.

How can I decompile .vmf and .vtf files into normal pictures?
I've already extracted the textures out of the PortalContent folderfile thing.

(I can go taking screenshots from the source SDK texture browser but that's a bit silly. I'll do this if there isn't anything thou.)

I would really love to fight in Portal setting with UT3, so if anyone has a way please do tell me how to get the textures.

UT3+Portal = luv

I don't know if just screenshotting the textures would be an adequate solution, what would you do about the texture mapping? It would come out looking very UT99-ish without maps. Very neat idea though, if it works out I'd like to download the texture pack in the UT3 format. I'd also like to play your Portal-on-UT3 maps

i'm pretty much 100% sure that taking the Valve OWNED textures and porting them into a non-valve game would = theft and copywrite issues

its not cuz im making freeware maps?

else I'll just ask, they won't loose money with what I'm doing here.

I know there are UT3 skins of characters that are owned by other companies, such as the Master Chief one, and i haven't heard anything about that being illegal, so maybe a map in aperture laboratories wouldn't be illegal? It sounds like a great idea for a map there and i hope it works out.

yeah it sounds great BUT you are still using ONE companies property to make maps for a DIFFERENT companies game and it being a freeware doesn't change that.

they let you use them for free for hl2 engine based maps because... it keeps the engine alive, and they make more money. but if you do this for a different engine, you are pulling attention away from THEIR engine, and i'm sure thats not allowed.

Copyright law is tricky. First off, the idea that because you're giving away your stuff that includes someone else's copyrighted work always makes it okay is false. If I include chapter 1 of the latest Tom Clancy book in my book, and give it away, I'm still infringing.

What you guys are worried about is fair use, which "provides for the legal, non-licensed citation or incorporation of copyrighted material in another author's work under a four-factor balancing test. " ( http://en.wikipedia.org/wiki/Fair_use ) These four factors are as follows:

Wikipedia wrote:
1. the purpose and character of the use, including whether such use is of a commercial nature or is for nonprofit educational purposes;
2. the nature of the copyrighted work;
3. the amount and substantiality of the portion used in relation to the copyrighted work as a whole; and
4. the effect of the use upon the potential market for or value of the copyrighted work.

I don't know of any legal precedents for fair use of things like maps, but I could see things like Halo skins and Portal textures being used in UT3 going either way. Essentially, there is no case law on the topic, so it's a very large gray area. However, I wouldn't worry about getting sued, because Bungie or Valve would likely just send you a cease and desist order to stop using their stuff.

However, remember, I am not a lawyer.

Hmm... is that Master Chief-skin not manually modelled? Or is it ripped from the game? Because ripping something from a game and using it in custom content for another game is something else than reproducing it yourself.

At least, I thought so. There's still the issue of the icon Master Chief, he's a trademark, I think.

illl go ask the guys at valve.

but in the meantime, can I have some sort of way of decompiling vtf and vmf files?

I had a quick look at the The Steam Subscriber Agreement and it clearly says that you're not permitted to use their work in other game engines.

-.-

can I remake it the textures?

I used counter-strike textures in ut2k4. I didn't release the map because it looks nothing like what it's meant to.
I suggest keeping this mostly to yourself and not sending it out of you happened to try and remake portal maps into the ut3 engine.
Most of all try not to ask us for anything because if you are caught in the act. Then valve will be looking at this forum for sure.

EDIT:
Questions are fine though.

VTF Edit, export textures as TGA, JPG, or BMP.

Google is your best friend

ty ill take a look into that. I mailed Valve but they havent returned mail yet. I'm expecting it anytime soon.

I asked if I could extract and decompile them from the Portal Content.
And then use it for myself.
Then I asked if I could publish maps for UT3 with Portal Content.

Hey I got an idea. I could make a Portal based CounterStrike map! They won't mind that.

No they won't. At least so I think. I mean, I see Half-Life stuff all the time in other mods (read: Source games, Portal is acutally simply a mod of Half-Life 2).

But you run in hell a lot of other issues. It's strongly disrecommended to mix game content, so you gotta include the textures in the map file. It's yet the question if that is allowed, but I think Valve doesn't really care if their stuff is used across Source games. As long as you note in the map description that you picked stuff of Portal.

But I'm getting slightly off-topic here...

3D realms is REAL tough when it comes to that sort of stuff. Yet i see their maps and textures map into other engines like half-life and once unreal tournament. I don't think they will care just don't say you made everything. Give credit to the Portal team as the post above said.

ofcourse I will give credit to the one who made the content.

I got some textures from Portal into UT3 and tried them out a bit.

Its hard to get the materials working right, and light doesnt bounce like it does in source, neither are there any light emitting textures.

You will need to place point_lights where you want light to come from.
And to get the right ambient light, you need to place some point_lights with lower brightness but with large radius in the middle of the room.

The challange is to get it as closely looking to a real portal map.
Below some screenshots of my crappy attempt.

It's harder then it looks like.

That's a really good recreation of the source engine's visuals. The Unreal engine is based more around making texture maps and actual 3D actors/static meshes look photorealistic, if you created bump maps for the textures it would look a lot better.

Anyways, I know quite a bit about copyright law through my work with t-shirts. Plus I have a lot of experience with mod work. It is 100% legal (and fun) to use textures from game A to create maps on game B. The only time you can get into legal trouble is if you sell your maps or mods with someone else's textures. When Valve says you aren't allowed to use their textures in other engines what they're really saying is "Please don't, or people might play your game instead " If it was illegal they would have used the word "illegal" however, they didn't use the word "illegal" because saying something's illegal when it isn't illegal is illegal.

So by all means, extract those textures, create bump maps for them, and make me a fun UT3/Portal map!

And tell people that it was the game Portal where you got the textures from! Maybe that will encourage more people to play it!
