* UVs in lightmap density view were shifting after building lighting. Fixed by considering the padding even if lightmap data is invalid * Auto generated lightmap UV was snapping charts to the whole padded lightmap instead of the actual valid center region. Fixed by subtracing 2 texels from the packing resolution * Also fixed some merging conflicts of auto gen #rb none [FYI] brian.karis, daniel.wright #jira UE-64923 #ROBOMERGE-OWNER: ryan.vance #ROBOMERGE-AUTHOR: yujiang.wang #ROBOMERGE-SOURCE: CL 5320218 in //UE4/Release-4.22/... via CL 5337165 #ROBOMERGE-BOT: DEVVR (Main -> Dev-VR) [CL 5387469 by yujiang wang in Dev-VR branch]
