fyi, here is the current setting of the psb file. I have tried turning on/off generate mip maps, and alpha is transparency and different wrap mode and different filter mode. All doesn’t works…
I have also tryed a few color profile in photoshop, but doesn’t work either.
I’m quoting this because while you may indeed need the importer plugin as well to support all of the features you’re using, the “strange” colouring shown in the OP is highly likely to be compression artifacts.
Note that you can control compression per-texture in the file’s import settings, so you don’t need to turn it off at the platform level.
Yeah this is more what I meant. I just thought of this panel:
And my brain thought ‘platform settings’, though import settings makes more sense.
I had the same sort of case as OP. Working on pixel art textures and was getting strange colours that weren’t present in my .png files. Turning off compression solved it. Though testing it, high-quality compression was getting the same results, though with tiny 128 x 128 or so textures, I don’t think compression is a big deal.
In my previous comment I was referring to the platform-wide project settings. I hadn’t realised that there’s a platform section in the texture-specific settings as well (is it new?).
