This test case has some noisey rendering due to not setting MipMaps on the terrain material's TextureArrays.
So I added MinFilter.Trilinear to fix this issue, and also added MagFilter.Bilinear.
I don't know much about the different MipMap settings, but MinFilter.Trilinear appeared to create the smoothest results for the terrain in this test case (and my own projects), so I went with that.
