Detailed Description

FMeshVertexChange represents an reversible change to a set of vertex positions, normals, colors and UVs Currently only a UDynamicMeshComponent target is supported.

Member Function Documentation

Apply()

void FMeshVertexChange::Apply ( UObject *  Object )

overridevirtual

Makes the change to the object

Implements FChange.

ProcessChangeVertices()

void FMeshVertexChange::ProcessChangeVertices ( const UE::Geometry::FDynamicMesh3 *  ChangedMesh, TFunctionRef< void(TConstArrayView< int32 >)>  ProcessFn, bool  bRevert  ) const

overridevirtual

FRegionMeshChangeBase API – passes the Vertices array to the ProcessFn lambda

Implements FMeshRegionChangeBase.

Revert()

void FMeshVertexChange::Revert ( UObject *  Object )

overridevirtual

Reverts change to the object

Implements FChange.

ToString()

FString FMeshVertexChange::ToString ( ) const

overridevirtual

Describes this change (for debugging)

Reimplemented from FToolCommandChange.
