What causes shimmering on distant walls or building while moving the camera?

[KainXVIII]

I don't know if its texture shimmer or shadows, which setting that i can tinker to get rid of it?

[SuiMachine]

Not sure if I know which one you mean. Got videos or something?

[KainXVIII]

Yeah, i think its shadows (maybe it was like the original and nothing can be done)

Not exactly sure to be honest. Shadows circle seems to be a swap between shadow cascades - kinda sucks it's that obvious. But shimmering, I honestly don't know - I had a look with render doc - normals seem correct. I was expecting that maybe dirt is done in some hacky way using a separate mesh, but that doesn't seem to be a case either.

Maybe it's just shadows and how they are rendered at a certain angles. HDRP had something to adjust this, but not sure about built in.

Ha-ha, this game is real mess technically it seems.

OK, so playing around - shadow bias seem to negate it, but that will make shadows detached from objects if the value is high, so there is maybe a possibility that there are building overlapping. Because I just noticed this:

OK, I think it's because some models have a separate model for receiving shadow and that one overlaps too closely with a model that's rendered. I could probably just scrap that one model and instead get the LODs to render shadows - I think PCs shouldn't have too much issues with it.

There is not much to Hook into unless I can find out what spawns those.

This should now be fixed if you enable replacing shadow meshes with LODs (available in options or config file). It won't work in runtime - it only applies when the mesh is being loaded.

Oh snap! I will try to test it today, thanks.

[KainXVIII]

I can swear that new shadow meshes setting worked at first when i installed a new patch, but then after some tinkering with settings (to see the difference) enabling/disabling this doesn't do anything at all and its not working (shadows flickering again). Weird!

[KainXVIII]

I think LOD Mesh shadows settings will take effect only after restarting the game, maybe you need to put the *asterisk after it 👍
Still, texture shimmering is still apparent (maybe its mipmapping issue?) but its minor compared to shadows (which is fixed now!)
