My Texture Sample Nodes are making my image textures "noisy". Almost as If they are pixelated

I am pretty new to using UE4 so sorry if this is a dumb question. But I can’t seem to find a way to make my textures that I import not have this weird noise to them.

They should look like this (the normal map at least)

They are just regular Jpegs so I can’t imagine what would be wrong. Any help would be great!

Also in case it matters, the texcoord node only seems to effect the top 2 textures “noise”. The normal map stayed messed up regardless.

Is it actually effecting your final material output. I grabbed your texture and I also get the same result of a pixelated mess in the Texture Sample preview, but the material itself looks fine. I also tested it on game assets when running the scene and it looks as expected. It looks like this might be a problem only with the preview swatches.

I know it’s an older post, but, the pixelated effect of the texture is probably caused because the texture is not power of two (512, 1024, 2048…), so the mipmaps are not generated.
