Grayscale Clusters Nanite. UE5?

Hi everyone.
Try to create modules for buildings and use Nanite for that. And I came across an issue…

If a mesh has low polycount then clusters are filled gray color… If I understand correctly this mesh isn’t showing as Nanite, right? Is it a bag or feature?

Left model is a just empty wall. Adding additional loops doesn’t make sense.
Right Wall has more dense polycount and works properly.

Is it bad or it works properly?

Thank you

Hello! @GC76rus If I understand correctly, you are asking if a mesh is Nanite when the cluster is gray in color.

The Nanite technology divides an object into smaller parts called “clusters.” Each cluster can contain up to 128 triangles, and the total number of clusters depends on the total number of triangles in the object.

An object with 128 triangles or fewer will have only one cluster (which in your case is the flat plane made of two triangles). The gray color probably is to indicate that the object is made of a single Nanite cluster.

For example, an object made of 64 or 128 triangles will have one cluster, while an object with 4096 triangles will have 32 clusters (with 128 triangles per cluster). See the image for an example.

So both of your mesh works properly as Nanite mesh. I hope this helps clarify your question.
