Unwanted ugly Borders on "my" textures

DXT1 textures, no alpha.
Whats going on there? (although its a shot from ut2004, the textures are actually indented for Unreal 1, 227g). Me was told I should check the alpha for boards but I dont get it, if I DONT use here any alpha ...

So can anybody explain me what I am doing wrong there?

That's the game rendering fault, something related to how the engine filters the textures.

Ok, I got a similar answer a few minutes ago
but HOW can it be that stock ut2003/04 textures do NOT have this bug, also hazels skybox textures. How can this be? DieHards Highres textures have this bug in ut2004 (if I load them there) either.
There must exist a trick to avoid this!

The trick that I know is stretching the texture by 1 pixel, or duplicating the last collum of pixel at the texture's border, something like that. But it would be much better to not having to do such "tricks" to get around "bugs".

Thats exactly what I do NOT want to do.. the textures do not fit then anymore... honestly I thought only those 8 bit textures would have this problem...

Like I said: Does not matter if I use Unreal 1 Ed (with 227g.. development version, not released for public so far, only for tester) or ut2004, only MY textures have this problem. :/

It's exactly the same as UT2004. In UT2004, after applying the textures to your skybox, you also have these slight borders. What everyone does is apply a scale 1.001. It gets rid of the borders and all textures still fit nicely.

Again, it works the same in UT2004, it's not a Unreal-specific problem AFAIK.

Ok, there is indeed a "trick"

actually in UT2004 you have to switch the UClampMode from UC_Wrap to UC_Clamp (otherwise even stock textures have this "bug")

From what I see there only skybox textures are using UC_Clamp in ut2004.

Sadly UEngine 1 does NOT have this option in the texture browser.
Only options called: UClamp and VClamp which have by default the resolution of the texture itself. So the question now: Does it anywise help to change there anything to "fix" this issue in uengine 1 as well? So far I was not successfull.

edit: ok for others

the most effective way for Skybox textures without stupid scale downs is (IMHO) to save the texturs in Photoshop over "Save for web" (under file). I dont know the technicial details but on this way you can even save high colour amount true colour pictures/textures easily for UT.
You just have to re-save the gif as bmp again in order to import it to unreal or ut.
Then apply for skybox textures NoSmooth, the difference is atomic small. Like I said, for me the best way.
