i have noisy or wavy problem in material

Hi i have problem i don’t really what i called noisy or wavy material problem!

However, this problem appears when I move from my place or when I move the player, but if I stop, it disappears. I have selected one LOD, but that did not help. I hope someone has a solution, thanks

see it here!:

Is that nanite or static meshes with normal LODs?

It looks like optimization switches LOD and then messes shadows a bit.

it was LOD mesh and i tried to remove all LOD But it doesn’t work and i convert it into nantie but same thing doesn’t work

It’s a mipmap issue.

The mipmaps are creating **moires pattern ** which btw happens in real life yet you get a lot of people who want games to look like the blurry post processed crap in movies.

There are two ways to fix this, lower the poly or pixel count on those parts of the mesh as the distance increases.
Or use TAA or TSR to blend past frames on the current frame.

The latter has severe downfalls being temporal ghosting and severe smearing in motion.


What happens when you use the mipmap bias CVAR and add .5 or 1?
(-1 to -15 makes textures more crisp but causes aliasing/shimmer while positive values do the opposite)

Edit: It’s geometric aliasing.
