MovieScene was targeted as its headers were at the top of profiling ShooterGame builds. Tested with -disableunity and -nopch. Current timings take ShooterGameEditor rebuild from 480s to 440s #jira none #rb josh.adams #preflight 624c97a63661c8f04a191889 [CL 19634779 by christopher waters in ue5-main branch]
