-Previous code said that the first PIE world was allowed to track the HMD. However sometimes the first PIE world is a dedicated server. Now the first non-dedicated-server PIE world gets HMD tracking. -This fix is a bit ugly to fit with hotfix rules. I think it would be better to cache this value somewhere, but didn't see anywhere that was not a public header. #jira UE-147360 [REVIEW] #rb Arciel.Rekman #preflight none #ROBOMERGE-AUTHOR: jeff.fisher #ROBOMERGE-SOURCE: CL 19929072 in //UE5/Release-5.0/... via CL 19930613 #ROBOMERGE-BOT: UE5 (Release-Engine-Staging -> Main) (v943-19904690) [CL 19932812 by jeff fisher in ue5-main branch]
