Layer with surface texture not visible anymore UE5

I’ve created a very basic island but suddently, a part of my paint layer is not visible anymore.

Can somebody explain this? I try to rebuild the scene and light but it’s stay like this.

Thank you for your help

Hey @LittleBandits3, welcome to the forums!
YOu could possibly have an orphaned layer, and you may need to re-paint and delete it. I have a bit of the documentation if you want to check it out: Paint Mode | Unreal Engine 4.27 Documentation
I hope this can help!

Thank you for this. I checked the documentation but it’s not related to the orphaned layer.

Because, when I continue to work the zone without layer … so the basic grey square are back to other portion of the landscape.

It’s realy weird. maybe it’s linked to this error.
