Hello. I was thinking of remaking some of my UT maps for UT2004 for a break from programming and I want to see if I can reuse the textures from the original UT (its legal). The problem is, they are much lower res than the UT2004 textures (generally 256x256 8-bit compared to 1024x1024 DXT1). Now I know that when you scale up a texture you loose resolution, making it pointless, but there are tricks like anti-aliasing which help approximate what pixels should be what colour when scaling up occurs. Its still not great *though*. I was wondering if anybody knew of any techniques to make this process worthwhile or any tools which are able to scale up images and do a good job at keeping detail high. I am using Photpaint (I am not an artist, so its always been fine for me) and using AA when stretching...but would like somthing better? Any suggestions?

i doubt they are 8 bit, and it doesn't really give you a blocky look when you up them, instead you just get a slightly blurred texture and because of that you can do the following. you can simply change the resolution of each texture to 1024x1024 or 512x512, then apply a sharpen filter, you can also increase contrast whcih helps the image look clearer. or if you have some spare time you cna up the resolution and add in the details lost back by hand.

First generation Unreal games did use 256 colour palletted textures, but they still looked good. I am not so worried about colour loss (there should be very little).

Ill take a look at sharpen filters and test the results.
