EZ Character + Unity: Character Sprite Sheet to Game Engine Pipeline

Generate directional sprite sheets in EZ Character. Slice in Unity's Sprite Editor. Wire into Animator controllers. Your 2D character in Unity — from concept to game-ready in hours.

Why this combination

Unity 2D character setup traditionally requires hand-drawing or commissioning every directional sprite frame — idle front, walk right, attack left, etc. EZ Character generates all directional frames of the same character in one pass. Import the sprite sheet into Unity, slice it, and wire the frames into an Animator controller with directional blend trees. The result is a game-ready 2D character whose identity is locked across every direction.

Step-by-step workflow

  1. 1

    Generate the directional sprite sheet

    Upload your character to EZ Character. Generate a multi-directional sprite sheet — 4 or 8 directions — at your target game resolution.

  2. 2

    Export sprite sheet PNG

    Download the composited sprite sheet. Each directional frame is placed on a grid with consistent padding.

  3. 3

    Import into Unity

    Drag the sprite sheet into your Unity Assets folder. In the Inspector, set Texture Type to Sprite (2D and UI), Sprite Mode to Multiple, and apply.

  4. 4

    Slice the sprite sheet

    Open the Sprite Editor. Use Grid by Cell Size slicing with dimensions matching your EZ Character frame size. Unity will create individual sprite assets for each frame.

  5. 5

    Create animation clips

    Select the directional frames for each direction. Create Animation Clips: Idle_Down, Walk_Down, Idle_Up, Walk_Up, etc. Each clip references the correct directional sprites.

  6. 6

    Build the Animator controller

    Create a Blend Tree with two float parameters (Horizontal, Vertical). Map each direction's animation clips to the corresponding blend values. Add transitions between Idle and Walk states.

Pro tips

  • Generate sprite sheets at native game resolution — Unity's pixel-perfect camera works best without scaling
  • Use consistent frame dimensions so Unity slicing is a single operation across the whole sheet
  • Add 1–2px padding between frames to prevent edge bleeding in Unity's texture atlas
  • Generate separate idle, walk, and action sheets from the same EZ Character reference

Frequently asked questions

What sprite resolution should I use for a Unity 2D game?
For pixel art: 16px, 32px, or 64px depending on your target display. For full-colour characters: 128–256px per frame. Generate at native resolution — upscaling introduces blur that Unity's point filter can't fully recover.

Does this work for Unity's 2D Animation package (bone-based)?
EZ Character generates sprite sheets — individual frame images. For Unity 2D Animation with bones, you would use the EZ Character frames as the sprite source and rig them with the Sprite Skin and Bone tools. The locked character identity means the rig works consistently across all frames.

Can I use this for 3D Unity characters?
For 3D, use EZ Character's turnaround output as orthographic reference for 3D modelling in Blender, then import the finished model into Unity. EZ Character does not output 3D models.

How many animation frames should I generate?
Start with idle + walk cycles at 4 frames each. EZ Character generates static references; you create the animation clips from them in Unity. For smooth animation, generate the character at multiple slightly-varied poses from the same locked reference.
