Hi!
This question should probably be on the Photoshop forum but I hope it helps someone else using Unreal.
I’m using Photoshop and exporting images in PNG, I noticed that some images appear with a white background when I remove the Alpha of the image.
How could I remove this white background?
File > Export > Save for Web (Legacy) Save for Web > PNG 24 : check Transparency
I have no idea what’s going on but it fixed the white border on images.
This is more visible when I’m using Min Gen Settings for small images that need Aliasing.
*Great explanation about this ( Thanks Ben Golus ):
