Problems with nanite mesh seams when using displacement

Hello everyone,

I recently started using nanites to use the Displacement mapping node on my material (on UE 5.3), but it causes problems with my meshes seams, some parts of my mesh are invisible.

Here is a picture of what it does, there are a lot of these invisible seems on all my mesh

I tried using another displacement map but it doesn’t seem to change anything, playing with the magnitude and center values doesn’t resolve it either.

If i disconnect anything from the displacement node, my mesh looks normal again.

Is there something I can do?

Sorry if i’m a bit unclear, I’m not used to making posts and I’m not very good at UE.
Thanks a lot

This is expected behaviour from nanite displacement. You need to modify the smoothing groups of your mesh to remove this issue. Have a look from here to see how you can solve it: https://youtu.be/UWrCA-t0v3U?si=F26fkCGsxtQ4ZDQd&t=1429
