Landscape component edges can become disconnected when using Nanite Tessellation at the edges of weight-blended layers.
1. Download the Licensee test project (see addl info URL)
2. Open the project. Observe that Nanite Tessellation is disabled, and that the landscape is crack-free
3. Enable Nanite Tessellation in the DefaultEngine.ini file, with
```
[/Script/Engine.RendererSettings]
...
r.Nanite.AllowTessellation=1
r.Nanite.Tessellation=1
```
4. Re-launch the game. Observe that the landscape is tessellated. Observe the cracks at the borders of components between weight-blended layers.
