Greetings UE Community,

This is my first post, and I hope you’ll be able to help me!

I recently added some meshes from FAB to try and build an environment. However, the cliffs, one of them shown in the images below, suffer from this weird grainy artifact when moving across them.

I’ve tried various suggestions via this community.. A few of which were to mess around with the Anti-Aliasing settings, disable Lumen, look at MipMap; however, all of them to no avail.

Hope you’re able to help in figuring out what this could be!

Thanks in advance!

It looks like something might be wrong with the normals of the mesh or its normal map. The lighting is weird and can cause these kinds of artifacts. Go into the world normal viewmode and inspect it, share an image if you’d like.

Hi @BananableOffense,

Thanks for taking the time to answer!

I tried looking at the World Normal, and nothing strikes me as weird or uncommon. Here’s the image:

But perhaps you have a more trained eye than me haha.

Thanks in advance!

I agree, those look correct. Since they are FAB assets I would suggest contacting the asset’s author since you can’t share the files to troubleshoot.

That’s probably a good idea, thanks for your help!
