In the engine

Hello! Can you tell image resolution and viewport resolution?

The image quality you see on the engine, once the textures are converted to DDS depend of some factors.
In you case, make sure you use the texture group UI, so the Mip maps are generated acordly.
To adjust those factors, open the image double cliking on it, and then you can change the mipmaps and compression values. Of course don’t forget to set texture group to UI

Now I imported the image from Photoshop and it doesn’t degrade. Previous image was from Paint
