Strange shadows

Hello,

I’m using automaterial from Sensei. I painted some layer textures on my landscape and enabled Nanite for using Displacement.

However, it’s now showing some shadow artifacts as I get closer to them and disappears when I get distant.

These shadows seems to be randomly placed.

When I disable Nanite, they go away.

Any idea what could be done?

Thanks!

Hey!

This sounds like a classic Nanite + landscape material interaction issue, especially when displacement is involved through auto-material systems like Sensei’s setup.

From what you’re describing (shadow artifacts appearing close up and disappearing at distance, and only happening with Nanite enabled), it’s most likely related to how Nanite is handling virtualized geometry combined with displaced surface details and shadowing.

A few common causes:

  • Nanite displacement not fully compatible with certain landscape material setups

  • Virtual shadow maps producing artifacts on high-frequency displaced surfaces

  • LOD transition mismatch between Nanite and non-Nanite fallback behavior

  • Auto-material layer blending creating unstable normals or depth changes

If it disappears when you disable Nanite, that strongly confirms it’s tied to Nanite’s rendering path rather than the material itself.

If you want, I can take a closer look at your setup and help you isolate the exact cause and adjust the material/engine settings so it renders cleanly again.
