Layer.ai

Layer.ai delivers intelligent animation tools to simplify the creation of smooth motion in 2D and 3D game environments. It automatically generates in-between frames from motion capture, smooths transitions, and even harmonizes animation sequences, reducing the burden of manual keyframing. Teams can upload skeletal data or mocap clips and Layer.ai will refine movement fluidity, eliminating jitter while preserving original performance nuances. This is ideal for indie teams without full animation staff or budget, enabling them to produce lifelike NPC behavior, combat moves, or cinematic cutscenes with studio-level polish. Layer.ai supports common formats and exports, making it compatible with Unity, Unreal, Spine, and other engines. Though pricing is enterprise sheet-based, it's a powerful solution for reducing animation pipeline time, improving quality, and enabling smaller teams to deliver complex animated content without compromising performance.
