Exported .pngs from Figma render with artefacts in Unity

Ay, I am facing the same problems. But funnily, I tried to post my design on Instagram. At first, I thought JPEG was causing artifacts because I looked at the original export; it does have artifacts. So I change to PNG. Great, no problem, no artifacts shown. But when I upload it, boom, artifacts.

I’m curious. This is my first two weeks designing using Figma for my Instagram business account. Usually, I use Adobe Illustrator.

Instagram, like any other social platform, compresses images and stores them as jpg. And this seems to be completely unrelated to the Unity problem in the original topic.

Did you try specifying the alpha channel premultiplication settings on Unity while importing?

Yes, I am aware of the compression. For my case, I am adding a noise effect to do the trick.

I know the reason of that
because Figma dont support export png with padding rgb channel

when game engine will use bi-linear or tri-linear texture filter, rgb channel will sample background color, and we will see the black or white edge

but adobe software will padding rgb channel when we export png, so you will find Adobe Illustrator export png is perfectly
