GeometryFlow: Added FCompactMeshNode, FComputeMeshPerVertexOverlayNormalsNode (convenient), and FTransferMeshMaterialIDsNode that applies FMeshAttributeTransfer based on two input meshes. Graph InferConnection() now is more clever and can infer connections in cases where a potentially-ambiguous connection is resolved based on what is already connected (ie if two mesh inputs, and one is assigned, infer that second one is intended) LODToolset: LODGraph now transfers materials and computes per-vertex normals before Simplify node, and Compacts afterwards (required for other downstream processes). LODProcess now handles multiple materials, and can re-use input materials if they do not require a baked texture or normal map. In repeat applications, previously-auto-generated StaticMesh Materials are detected and removed from the material set. Normals and Tangents are explicitly computed for stored HiRes source and LOD0, and build settings updated appropriately. #rb none #rnx #jira none [FYI] tyson.brochu #ROBOMERGE-SOURCE: CL 15470041 in //UE5/Release-5.0-EarlyAccess/... #ROBOMERGE-BOT: STARSHIP (Release-5.0-EarlyAccess -> Main) (v771-15082668) [CL 15470044 by ryan schmidt in ue5-main branch]
