The mesh in the repro project contains a transformed convex collision, which can be moved freely in the mesh editor, so the transform must be applied in following code block. (Also see TODO).

FORCEINLINE_DEBUGGABLE void ExportRigidBodyConvexElements(UBodySetup& BodySetup, TNavStatArray<float>& VertexBuffer, TNavStatArray<int32>& IndexBuffer,
	TNavStatArray<int32>& ShapeBuffer, FBox& UnrealBounds, const FTransform& LocalToWorld)
		if (ConvexElem->GetChaosConvexMesh())
			// TODO use ConvexElem->GetTransform?() transform?
//			ExportChaosConvexMesh(ConvexElem, LocalToWorld, VertexBuffer, IndexBuffer, UnrealBounds);
			ExportChaosConvexMesh(ConvexElem, ConvexElem->GetTransform() * LocalToWorld, VertexBuffer, IndexBuffer, UnrealBounds);
Steps to Reproduce
  1. Open attached project on UE5.0 [Link Removed]
  2. See navmesh in the level


A navmesh is generated where no collision exists.
