--alpha-mode 1: Fills the alpha channel with both white and black and extracts the difference from each result.--alpha-mode 2: Upscales the alpha channel by itself, as a fake 3 channel image (The IEU way) then combines with result.--alpha-mode 3: Shifts the channels so that it upscales the alpha channel along with other regular channels then combines with result.

| More obvious inside of Cupscale (with the squares background). Mode 1 differential: This makes the left hand "web" quite transparent (actually more noticeable in cupscale). It also alters the colour of the red symbol to be very dark red. Mode 2 separated: This seems to be the best balance and colour representation. The alpha around things isn't as extreme, only thing is the top right wolf symbol has a fair bit of white around its now more apparent edges Mode 3 channel: This seems to messy up the detail of the textures. The red symbol especially is a complete blurry mess. Problems previously here are null and void - was due to Low Violence setting (and the letters scaling was just always the same for whatever reason). |
| tcn01_blst02 - These 3 may be just upside down...or something to do with the de-DDS AI run on them? mmmm | |||||

Might try to redo all the scaling with transparency on and using mode 2 with 8 bit transparency.

Oddities...but looks like it's the same regardless of texture upscaling! Bad tileset juju, Zwerk has been informed. Not just my system.

So they do upscale just...not great. Upscaled versus normal - North Road, NWN Chapter 2 top left.
