Runtime notes: - Removes 'smart name' usage across the animation systems. - Changed curve blending from a uniform array (sized per skeleton) to a sparse array of sorted named values. Blends and other combiners are performed using a dual iteration 'tape merge'. - Skeleton curves are no longer guaranteed to cover all curve names that can be found at runtime. Editor notes: - Curve metadata (flags, bone links etc.) is still present on the skeleton, but can also now exist on a skeletal mesh - Curve metadata (for morph targets) is still populated on import - Curves can now be used arbitrarily at runtime New features: - New Find/Replace dialog that allows for batch-replacing curves and notifies across all of a project's assets - New curve debugger tab in various Persona editors that allows for viewing curve values live. This also now allows viewing curves for specific pose watches. - Pose watches now output curve tracks to the Rewind Debugger #rb Jurre.deBaare,Nicholas.Frechette,Sara.Schvartzman,Helge.Mathee,Kiaran.Ritchie,Jaime.Cifuentes,Martin.Wilson,Keith.Yerex,Andrean.Franc (and more!) #jira UE-167776 #jira UE-173716 #jira UE-110407 #preflight 63fc98c81206d91a2bc3ab90 #preflight 63f3ad4f81646f1f24c240c2 [CL 24421496 by Thomas Sarkanen in ue5-main branch]
