This might sound like a stupid qustion since I already know that it doesnt affect how it loads in the game already. Atleast it hasnt.

I started working with making new textures. So I opened up one of the landscape textures from my textures folder, saw that it was only
512 x 512 so I upped it to 1024 x 1024 made the texture and saved the it. Loaded up fallout and it looked a little of, so i went back to see it.

I have dds thumbnail viewer, saw that my other textures I did was fine accept the one I upped to 1024 x 1024, it has a huge black border around the image.

Started up photoshop, loaded the dds file, and it looked just fine

any one know why I am getting this black border?

hmmm. I'm going to guess mipmaps?. but I honestly haven't a clue. I'd have to look at the textures to really see what is happening.

Also simply resizing the texture to 1024x1024 will not really make it more detailed, though it will fend off smaller mipmaps being rendered at closer view distances.

particulary, do not do this with any normal maps that have already been compressed! it'll just degrade into a pile of rubbish.

How would it not make it more detailed if I am putting the detail into it?

I am new to texturing, haven't even read a tutorial on exactly how it works. but they seem to be turning out right.

I fixed my original problem. I was saving the alpha channels when I saved the dds file, after removing the all of my problems disappeared.

Does anyone have a good site to learn how texturing actually works.

You didn't say you put more detail into it!

Well for a start, your biggest problem is the lossy format. all vanilla textures have already been compressed, DXT . And contain compression artifacts. simply resizing the image will just up sample the pixels to 4x the size the were as best the progrma can, often it adds a little anti alliasing. but thats it. really you essentially just have bigger pixels, no new detail is really added. add that to the fact you are again going to compress the textures again, thus adding further pixelation.

Unless you are using some tool that has a respampling and extrapolating function, what would basically try to add in the missing pixel data, even then removing the compression artifacts is nigh on impossible. But you can get some sort of result by using the up sampled orginal texture on one of your own scratch made one. using it as a color layer, or trying to lift details out of it.

this kind of recontruction is quite time consuming, especially if you want to rebuild a normal map proper.

Alright I understand what you are saying. I also apologize for the detail thing, I just opened the base dds file to see what it looks like, the created a new file and saved it as a dds file once I was done using some extension I found online for photo-shop. Thank you for all of your help. It was very useful. And for the explanation.
