Hello everyone!
I am original author of this mod.
I would like to inform that the final version was released.
I agree that Kotor is ageing game and probably even four times upscaled vanilla textures may be not enough, but keep in mind that it has around 2300 textures (GUI, effects and etc excluded) and it is very huge amount even when making wth the help of AI, not to mention making those from scratch (figuring UV mapping, creating new textures, testing and etc)
And yes, alphas are intact, as I did not upscale those with AI (AI does not upscale those correctly even if you tweak it to do so). And I did not use any automatic transfering of alphas (there are already problems in some mods using this method when alpha must be 100% black, but somehow during this transfer it becomes 98% black and then transparent models occur in-game). I upscaled alphas using bicubic filter and transfered to upscaled textures, all by hand, texture by texture.
On the bright side with this mod keeps game's original look with way more sharper textures.
Regarding before and after pictures, well due to jpg compression most people won't even see the difference in those pictures (as not everyone has monitors precise enough in color reproduction and etc.), but I may add some as I finally finished the mod.
Take care!
And Merry Christmas!

P.S. Thank you Salk for sharing this here!
P.P.S. Regarding TXI info. I just discarded .tpc format as it was giving too many issues (problems with mipmaps, seams, transparency; don't know if it was just a problem of a tool, but took too much time to transfer .txi info anyway). When making .tga you don't need any .txi info as game provides it by itself.
