Animation Clip Assembly in Game Timeline: Turnkey Service
We integrate and configure Unity Timeline for cutscenes and gameplay events. This is not just a "cinematic for cutscenes" — it's an orchestration tool that synchronizes animations, audio, object activation, Cinemachine cameras, and custom signals with frame accuracy. When set up correctly, the entire cutscene is controlled by one PlayableDirector. When done hastily — a chaotic collection of Coroutines scattered across scripts that desync when FPS changes. We solve such problems turnkey: from analysis to deployment. We'll evaluate your project for free — contact us.
Animation Tracks and Binding
Each animation track is bound to an Animator via Output binding. The problem when reusing a Timeline Asset across different characters: bindings are stored in the PlayableDirector, not in the .playable file. Solution: director.SetGenericBinding(track, newAnimator). This is convenient for dialogue systems — one Asset works with any NPC.
Clips are managed by Ease In/Out and Clip Transform. Ease In/Out blends from the neutral pose to the animation. But the neutral pose is not a T-pose or idle, but the last pose before the Timeline starts. If the character was standing with arms down, and the cutscene starts with a hand at the face — without proper Ease In there will be a pop. We create a short transition clip (0.5–1 sec) that smoothly transitions into the first pose. This clip is placed first on the track with minimal Ease In, then overlap with the main action. The transition works regardless of the character's state.
Blending Clips: Override vs Additive
By default, the track is in override mode (full control of the Animator). For simultaneous layers (body walks, head turns, hand gestures) we use multiple tracks with different Layer Weights or one track with an Avatar Mask. An Avatar Mask on a clip limits which bones are controlled. Pattern: track 1 (Full Body) — idle, track 2 (Upper Body) — gesture, track 3 (Head) — look-at. Blend is controlled by Track Weight.
Problem: two tracks with overlapping masks compete for a bone. Timeline uses override blending — the last track wins. If additive (sum of transforms) is needed, the Track Mode switches to Override with Additive Clip. Configured via the track's context menu, not the inspector.
How Signal Track Synchronizes Gameplay?
Signal Track is a mechanism for sending events from the timeline to game logic without direct dependence. Signal Emitter on the timeline → Signal Asset (ScriptableObject) → Signal Receiver on a GameObject with a subscribed method. Usage: enable hitbox on attack frame, trigger particle at explosion moment, switch AI state after dialogue. Without Signal Track, this is done via Animation Events or Coroutine with WaitForSeconds — both break when timing changes. Signal Track is more stable and easier to maintain.
Important: the Signal Emitter only triggers during normal playback. For debugging, use the Retroactive flag on the Emitter.
Cinemachine Integration and Camera Editing
Cinemachine Track is an editing table for cameras. Each clip is one virtual camera. Blend is controlled by Ease In/Out overlap. Problem: when transitioning between cameras with different Look At targets, "floating" occurs. Fix: Blend Hint Override Lookat On Blend = true on the second camera, or manual control via CinemachineBrain.m_DefaultBlend.
| Blending Mode | Description | Typical Use |
|---|---|---|
| Override (default) | Full control of Animator | Cutscenes where one animation at a time |
| Additive | Sum of transforms | Additional gestures on top of locomotion |
| Avatar Mask | Control of selected bones | Separating body and head |
