Syntax
struct FGenericMeshSelection
Remarks
FGenericMeshSelection represents various types of selection on a Mesh. This includes various types of indices that could be interpreted in different ways.
In addition, "Render" geometry is stored, which can be used by higher-level code to draw the selection in some way (eg a selection highlight)

Variables
| Type | Name | Description | |
|---|---|---|---|
 |
TArray< UE::Geometry::FIndex2i > | EdgeIDs | Selected edges, represented as index pairs because for many selections, using a pair of vertices defining/on the edge is more reliable (due to unstable edge IDs) |
 |
TArray< int32 > | FaceIDs | Selected triangles/faces/regions |
 |
TArray< UE::Geometry::FSegment3d > | RenderEdges | Set of 3D lines representing selection (in world space) |
 |
TArray< FVector3d > | RenderVertices | Set of 3D points representing selection (in world space) |
 |
UPrimitiveComponent * | SourceComponent | Component this selection applies to (eg that owns mesh, etc) |
 |
ETopologyType | TopologyType | Selection type |
 |
TArray< int32 > | VertexIDs | Selected vertices or "corners" (eg of polygroup topology) |
