I have recently started using UE and am in the process of adding some assets to an initial block out of my level. However my diffuse/base colour appears blurry both in the viewport and when playing the level. I am using a 2k texture but have also tried a 1k texture and both produce the same result.
I have changed the MipGenSettings of the texture to NoMipMaps and have also changed the texture filter to “nearest”, but none of these worked on improving the quality of the texture in UE.
besides making sure you set the scalability of the engine to " epic" all I can think of is being sure you saved as .png 8bit, or .tga.
also, for the love of performance be sure to keep mipmaps on
worst cases, it helps to clean your cache, which helped occasionally with older versions:
which should be around
