Colors without transparency before export

Colors without transparency after export (and modified colors cause that was the need)

Why has this never been fixed? Who needs PNG's to work this way?

Two decades of people complaining about this problem, and photoshop has never fixed it for what reason? Shouldn't it be considered embarassing that the defacto image program can't export a usable PNG for anything but a twitter post?

How did you export the pngs exactly? PNG-24 via Save for Web?

I do not know eactly what process i used for those images but the results after saving are kind of random anyway.
Hair texture exported from substance painter

Save for web (png 24, and even if this did work it is astronimically slow, it's insane)

Quick export as png

Export as PNG (ensuring transprency is enabled)

Save a copy

Save As works SOMETIMES, other times it does this for no reason. Meaning even if it can work i hae to double check the file every time.

This has been a known problem with photoshop amoung game developers for over a decade and it's never been reliably fixed. People used to use SuperPNG but now that seems to be gone or just too old to work. There's multiple threads on this issue spanning years and adobe wonders why people are frustrated with the subscription.

This is exactly why I don't bother with Photoshop's PNG export. And the fact that 8bit PNG files cannot be saved with full transparency is just ridiculous.

I use Color Quantizer to open the PSD file (drag it into CQ) and export a correct PNG file. It offers advanced PNG export and editing options that cannot be found in any other visual PNG export software, including full control over how alpha is treated and exported. It is by far the best PNG export and optimization tool out there.

The official website only runs via http, so a browser will warn against visiting it. But it is safe otherwise.
