Beyond Skyrim - Bruma Upscaled Textures (BSBUT)

Will write a better description later maybe. If you look at my profile you can see I upscale a lot of stuff and info, blah, blah.

This:

I upscaled textures of clothing, armor, weapons of Beyond Skyrim - Bruma SE with ESRGAN. I made this for me, but since the mod authors are gracious, I can share this with you. Theoretically, I might do the rest of the expansion, idk. Cleaned Textures of the whole expansion now available, only tga. So you need to assemble.

Is this a flawless masterpiece?

No, this is something my computer did while I played animal crossing, because computer smart. If an actual texture artist made something at 4x resolution of the original, it would be better than mine. But alas, there isn't, and I am lazy and untalented. Therefore, you get AI textures.

Kartoffel, does this really need to be 4x?

Sure, why not.

Requirements:

Skyrim Special Edition - wow

Beyond Skyrim - Bruma SE - as expected

Process:

Extract textures from bsa

All textures: Remove BC1-3 compression with Bc1-smooth2 model.

Diffuse 1024x1024 and under: Upscale 4x with interpolated model Manga109 and WeaponsAndArmor @ 0. 8, Alpha channel is box model.

All textures: Compress to BC7.

Modules:

Weapons: This actually includes weapons of the third era, so you can just download this.

All_Cleaned: This is the whole expansion cleaned of artifacts. Only 1x, available as TGA images, so you need to run it through Cathedral Assets Optimizer. Useful as a modder's resource.

Resolution:

4x: Diffuse equal or less than 1024x1024.

1x: Environmental, Glow, Normal, Specular, Cubemap, Diffuse larger than 1024x1024.

If diffuse is larger than 1024x1024, e.g. 2k or 4k, I don't upscale. Just clean like everything else.

4x does not mean 4k. It is the scaling factor.

If original is:

512x512, output is 2048x4096 (2k)

1028x1028 (1k), output is 4096x4096 (4k)

Why are certain things not upscaled?

The quality is improved, but the need to upscale is excessive in my opinion. Quality is improved by removing BC1-BC3 compression. Upscaling something that is already 2k or 4k is pretty pointless and massive. E.g. A 4k resolution, 21MB file upscaled is 16K, 336MB.

Difference of block compression BC1, BC3, and BC7:

In dds texture (the textures skyrim uses), compression via BC1, and BC3 (with alpha), is blocky. Because of this, in original Skyrim, people sometimes leave textures uncompressed. Uncompressed has a big file size.

With the new block compression, via BC7, it is nearly the same quality as uncompressed, but has the same size as BC1, and BC3. However, this is only supported in Fallout 4 and Skyrim SE.
