nathan mitchell	8f2f94554c	UVEditor: Performance tuning to improve runtime speed of rebuilding the UV overlays and meshes when edits or channel switches are performed. This significantly reduces the allocation and search churn when switching UV channels on high poly count meshes. ... This review duplicates and replaces the original review https://p4-swarm.epicgames.net/reviews/21689505 on //UE5/Main, primarily to bring it directly into 5.1 instead of robomerging from Main so close to the hardlock date. The issues discussed in the original review should now be addressed here. #rb Jimmy.Andrews #preflight 633330007b582f58abcc30b4 #jira UE-157828 [CL 22239923 by nathan mitchell in ue5-main branch]	2022-09-28 22:01:32 -04:00
semion piskarev	abb3f3a513	UVEditor: Support unset UV's, add unit tests, move UVEditorToolUtil into a separate module so that it can be tested in unit tests. This also fixes very poor performance when updating lots of triangles by using "unsafe" insertions where relevant. ... #rb Lonnie.Li #rnx #jira none #preflight 618452e80172ec00013f7211 #ROBOMERGE-AUTHOR: semion.piskarev #ROBOMERGE-SOURCE: CL 18066788 in //UE5/Release-5.0/... via CL 18066954 #ROBOMERGE-BOT: STARSHIP (Release-Engine-Staging -> Release-Engine-Test) (v889-18060218) #ROBOMERGE[STARSHIP]: UE5-Main [CL 18066977 by semion piskarev in ue5-release-engine-test branch]	2021-11-04 19:59:04 -04:00
