Hey. I can’t figure it out, look at these circles. What it is, where they came from and how to remove them. Help please.

I realize that I probably made a stupid mistake because of carelessness.
This is due to texture compression or quality loss
- You can try using different compression methods like UserInterface2D (R8G8B8A8) (make sure to have the source files in the original imported directory to be able to see changes)
- Using other file format, like TGA or PSD (even tough UE4 converts TGA to PNG in the end, but i noticed some PNGs issues that actually imported fine when using TGA instead)
- Make sure you didn’t exported the image with lower bit depth. Bit depth defines how much data is used to represent the image 8 bits per channel is the standard (24/32 bits in total for “no alpha”/“with alpha”)
But still, you might not expect that much image quality, unless using a FloatRGBA as format “HDR Compressed”, that wont even import properly using PNG or TGA, only using .EXR
P.S.: there’s also “texture dithering” technique to make the texture have more “smoother” gradients.
I love you. Thanks.
