Nov 1, 2024In November 2024, delivered two focused changes in galacean/effects-runtime to improve animation reliability and playback stability. Feature: Timeline Property Clip Time Normalization introduces time normalization for property clips within the timeline, ensuring property animations scale correctly with each clip's duration. Bug fix: Interactive Item Handling During Playback fixes incorrect removal/addition of interactive items during playback when the component is disabled, stabilizing composition state during runtime. These changes reduce manual adjustments, prevent playback glitches, and improve reliability for complex timeline-driven scenes.
