Demonstration:
Acting Studio and Physics
- Realistic physics and combat: collision of actors is complete vanilla. Animations for taking damage, falling, being knocked down, and death are supported.
- Mob actors: replace any actor model with standard Minecraft mobs or creatures you create.
- Organized timeline: grouping by folders, dragging, hiding tracks, and single‑window view mode.
GUI Recording
- ** Now you can record in‑game GUI, and they will be displayed in flashback mode.
Controls on the 3D view screen
- 3D tool: move and rotate actors in the scene using simple controls of the 3D tool.
- Keystrokes: step‑by‑step adjustment of actors positions using the arrow keys on the keyboard.
- Quick alignment: rotate characters around light axes, turn them to face the camera, or lower them straight to the ground.
Entity settings
- Skin Manager: apply skins by username or from a local file, and configure dynamic skin switching over time.
- Equipment Studio: use an interactive menu to edit armor, custom inserts, and items in hand.
- Glow and name plates: choose your own glow colors for outlines using preset palettes, and dynamically change the name plates.
- Scaling and opacity: smoothly adjust transparency and scale entities.
- Entity display: fully customize the entity displays.
Studio timeline and cinematic keyframes
- Cinematic key frames:
- Add motion blur, smooth opacity transitions, entity scaling, and world slicing directly to your timeline.
Custom Export
- ** A system for separate export of the world and entities with a transparent background has been added.
