Double & flickering foliage issue (City Park example) [UPDATED - 1/2 fixed]

@Jarrastafari

Thanks for the suggestions guys. I’ve fixed the issue by opening a copy of the project in 4.26; though I suspect making a copy in 4.25 would have also solved the issue, as it seems like a bug.

I’m now trying to tackle the issue of flickering/shimmering foliage, as seen in the grass here… any ideas what this is?

Distance field shadows need disabled on the foliage perhaps?

Have you tried disabling Sky denoiser? (Or maybe AO denoiser, GI, denoiser… but I think it’s Sky’s)
