The year is 2052 and the world is a dangerous and chaotic place. Terrorists operate openly, killing thousands; drugs, disease and pollution kill even more. The world's economies are close to collapse and the gap between the insanely wealthy and the desperately poor grows ever wider. Worst of all, an ages old conspiracy bent on world domination has decided that the time is right to emerge from the shadows and take control. No one believes they exist. No one but you.

Post tutorial Report RSS S3TC Compression

the site that i posted my s3tc on is down so i should post it here

Posted by on - Intermediate Textures

S3TC stands for S3 Texture Compression used in the graphic mod new vision it allows you to create high resolution textures and merge them with low quality meaning high quality gets viewed ingame note unrealed wil still show them at low quality

lets get started with the tutorial you wil need to download these files
or if you dont want like development kit click link below
if link throws you inside the archive press ctrl+s or go to file and click download
this tutorial is based on the files inside of this download but can still be done with original since only change is size and a few folders

to use S3TC make a texture in high resolution with the power of 2 (256x256 or 512x512 or 512x256 as long as it multiplies with both numbers)

note you can go highter like even 4096x4096 but its your choice since the files get big

save the full resolution as a bmp(RGB8 or index) in a map were you can easely pick it
save the low resolution as a pcx(index only) in a map were you can easely pick it

note added a textures map with high and low to easely sort the files

open up unrealed import the full resolution and the low resolution in a package with the same name(not both in one they have to be seperated)

save the full resolution utx file into the high folder located in the s3tcmake folder
save the low resolution utx file into the low folder located in the s3tcmake folder

launch the S3TCConverter.Bat and see how the magic is performed

the new utx file is the compression of the utx file in the high and low folder
drag/copy and paste it into your texture folder(overwrite if needed)

Note : textures need the same name in both packages

Note : it wont mismatch if you used the textures in a map unless you did something wrong if so retrace your steps in this tutorial
