Title: External upscaled sprites
Post by: ncuxonaT on November 12, 2015, 06:55:51 pm

Hi!
I've found great 2x upscaler, but unfortunately it's impossible to use it as shader/postfilter. I can upscale sprites as separate images and save them in png format.
I wonder if it possible to load sprites from external png files?
Examples:

Damnit, the body armored trooper is spinning in the wrong direction.

I would love to see how you're doing this. :X

But not sure how with a .png sprite sheet.

Looks like Waifu2x (https://waifu2x.udp.jp/).

You can't import upscaled sprites into OpenXcom though.

I fail to see the purpose, there's already over a dozen various blur filters built-in into the OXCom, that do the exact same thing on-the-fly... Maybe if someone made *actual* hi-res gfx, but that's an insane amount of work :)

That's right, it is Waifu. Usually Waifu gives better result than built-in blur filters. Here's comparison Waifu vs xBR:

well the good news is that replacing sprites is easy, the bad news is unless it can be turned into a real-time filter, you'd have to make a fairly extensive rewrite to the graphics core to support externally upscaled sprites.

Still looks krappy, but at least it's noticeably better than any in-game blur filter now.
