Some workflows and information on texture creation for Overhaul.

4x Upscaling Existing Texture DDS

This is a multi-step process, but reasonably simple, to obtain a upscaled PNG file.

1. Crunch the DDS file back to PNG (this "flips" it)
2. Run Cupscale with the models below in a chain (first one, then the other) for the texture (or set of textures):
   1. 1x_artifacts_bc1_free_alsa.pth
   2. 4x_BSRGAN.pth
3. Save resulting PNG as the base diffuse (xxx_d.png) file.

Then you use this as the basis for the others, and if you need to scale back to 2048x2048 or smaller use Crunch to do it at the DDS stage.

4x Upscaling Existing Texture TGA or other

Same as above but you can avoid the Crunch step; just run Cupscale on the TGA file with 4xBSRGAN.pth model being run. It'll self-convert to PNG automatically.

Upscaling Textures with Transparency

This can be a big pain in the arse. Things like leaves or whatnot. Some notes to follow and check out 4x Texture Upscaling pages for some attempts at formalising it.
