I am currently working with Unreal Engine 5, and I’ve encountered a problem when importing PNG format images into the engine.
The issue I’m facing is that when I export an image with a transparent background in PNG format from Photoshop, the image appears to have a white background when imported into Unreal Engine 5. This issue is causing unexpected results in my project, as I require the images to maintain their transparency.
I’ve attempted various settings adjustments both in Photoshop and Unreal Engine, but I haven’t been able to resolve this problem. I’ve also ensured that the alpha channel correctly represents transparency in the PNG format image.
I’m reaching out to the community in the hope of finding a solution or guidance on how to correctly import PNG format images with transparency into Unreal Engine 5. If you have any insights, suggestions, or if you’ve encountered a similar issue with PNG format images, I would greatly appreciate your assistance.
Thank you in advance for taking the time to read my message and for any help you may be able to provide. I look forward to hearing from you.

I too have encountered this issue with no fix so far unfortunately.
We’re also having this issue. I wanted to add some details.
-When importing a PNG Unreal 5 will add white padding around the image. Rather than adding padding that matches the image profile. This white padding causes artifacts to appear when the image mips tp lower resolutions.
-I’ve tested multiple engine versions. This issue doesn’t exist in 5.0 but does exist in 5.1,5.2 and 5.3.
-I have textures that were added to our project in 5.0 that have the correct padding. If I reimport them now(project is now 5.3)the padding will break and turn white.
Example of what this looks like. Right image is correct, left is with bug. This happens to every png I import on the latest engine version. PNGs are created with vector shapes in PS and AI, there is no reason for a white padding to be generated. These same images imported fine on 5.0.
Video of issue white padding creates when textures mip. Adjusting mip and filter settings can make this less bad but doesnt fix the issue.
Temporary Fix.
If you can not wait for Epic to fix this there is a work around.
-Import your textures into a 5.0 project (Im using 5.0.3). They’ll import correctly.
-Migrate them to your 5.1, 5.2, or 5.3 project.
Not ideal… but if you need them to work ASAP…
