Images in UMG do not correctly inherit the texture’s filter setting. The only way around this is to make a material, and then choose the material in the UMG Image component instead of choosing the texture directly.
Here is what choosing the texture directly looks like
It sounds like you have been able to reproduce this in a clean project, is that correct? If so, do you have steps that we can use to reproduce this issue reliably on our end? Is this only with the particular texture that you have shown in your image, or does this occur with any texture?
I’ve attempted to reproduce this using a few different textures, but have been unable to do so. Could you send me this “Score” texture that you are using so I can import it into my project and see if I can get the same results? Thank you.
Just to be clear this is for low resolution pixel art files. If you’re attempting to do this with something similar to a photograph the difference might not be enough for you to tell.
To make it easier to tell you may have to zoom in on the image, as these files are low resolution.
Here is another example, the first one is using the texture directly and the lower one is using a material. Only the lower one is properly inheriting the Nearest texture filtering.
I have been able to reproduce your issue, and have entered a bug report (UE-24798). Thank you for your report. I will provide an update on this issue when it becomes available.
