Hi Quality, thanks for posting images of the issues you are having with UMG. I was having the same issue with the jagged rendering of textures in UMG that you are experiencing. What I learned is that you should avoid scaling your textures and images in UMG’s layout editor. Its the scaling that is causing the horrendous rendering. You need to render your graphics at their native size without scaling them. I know this should not be the case, and it doesn’t affect sprite rendering, but it is what is causing your issues.
There are of course other rendering artifacts with the alpha channel that are also causing me trouble as I’ve written about above. but give my suggestion a try… all the texture filtering settings that I’ve tried don’t help at all. I think the subsampling routines that UMG/Slate employee doesn’t handle scaling very well at all!
Good Lock,
W.
