- remove FDynamicMesh3::Timestamp (unused), rename Shape/Topology Timestamps to Shape/TopologyChangeStamp, change to atomic<uint32> - add FDynamicMesh3::bEnableShapeChangeStamp, default to false, to disable ShapeChange tracking. Add ::SetShapeChangeStampEnabled() and ::HasShapeChangeStampEnabled() to configure. - replace FDynamicMesh3::UpdateTimestamps() with UpdateChangeStamps() - add bTrackChange param to FDynamicMesh3::SetVertex(), optionally updates ShapeChangeStamp (if enabled). Default true. Remove SetVertex_NoTimeStampUpdate(), update call sites. - add FDynamicMesh3::GetChangeStamp(), returns combination of Shape and Topology stamps as uint64 - rename TTriangleMeshAdapter::GetTimestamp() to GetChangeStamp(), update usages - remove TPointSetAdapter::Timestamp() (was not used in code) - update TMeshAABBTree3 to use GetChangeStamp(), update internal checks to call IsValid() instead - update TFastWindingTree w/ similar changes - update calls in UVEditor, may require further updates #rb semion.piskarev #rnx #jira none #preflight 6126904c72e9eb00011434fe [CL 17310271 by Ryan Schmidt in ue5-main branch]
