Sprites & Textures showing white outlines

Hi everyone!

I’m making a Top-down 2D game in Unreal.
Currently, I’m importing textures in .png format (exported by an artist using Photoshop), and, once imported, I convert them to Sprites to place in our level.
I assign these sprites a Translucent Material to manage sprite overlaps.

However, I noticed that sometimes (especially when I import textures that are 2 parts of a single object) these textures show a faint white outline that’s not visible in Photoshop.

May this issue be related to Unreal (either import or rendering)? And, if yes, know a way to prevent this from happening?

Thank you so much in advance :pray:

Below are some reference of the issue:

  1. view of the sprites in UE editor, when put close together to form the object
  2. view of the sprites in UE editor, separated
  3. view in Photohop

The white could be the background color in photoshop - change the background color to the tan color would help remove it. It could be indicating there has been a resize done in photoshop and it has smoothed the edges - one possible explanation anyway…
