Advanced rigging and export techniques in fragMOTION

Create Retro Game Assets with fragMOTION: Step-by-Step Projects

Overview

A compact project-based guide that shows how to make retro-style 2D/3D game assets using fragMOTION. Covers pixel-art-friendly modeling, low-poly sprites, animation, palette management, and export for common engines (Unity, Godot, GameMaker).

Projects (progressive)

1. 8-direction character sprite (16×24 px)
2. Tile-based environment tileset with parallax layers
3. Simple enemy with walk and attack cycles
4. Breakable props with particle-friendly pieces
5. Boss sprite using layered meshes for animation

For each project — step-by-step workflow

1. Project setup: create correct canvas size, frame rate, and palette.
2. Blocking: rough low-poly mesh or 2D plane layout to match pixel proportions.
3. Pixel-friendly modeling: snap vertices to pixel grid; use minimal polygons for crisp silhouettes.
4. Texturing & palette: paint using limited palette, incorporate dithering and outline colors.
5. Rigging: set simple bone hierarchy; use IK for legs when needed.
6. Animation: keyframe poses, in-between frames, and apply onion-skin to maintain pixel consistency.
7. Refinement: clean edges, check silhouette at game scale, tweak timing for readability.
8. Export: choose sprite-sheet or mesh-export options; optimize atlas and alpha settings.

Tips & Best Practices

• Palette: limit to 8–16 colors per sprite for authentic retro look.
• Silhouette: test at final game resolution early and often.
• Timing: use 3–4 frame walk cycles for chiptune-era feel.
• Scaling: design at native game resolution to avoid interpolation artifacts.
• File sizes: trim transparent space and pack atlases to reduce draw calls.

Exports & Engine Notes

• Unity: export PNG sprite-sheets; set Filter Mode to Point and Compression to None.
• Godot: use AtlasTexture or AnimatedSprite with region frames.
• GameMaker: import as sprite strip, set origin and collision mask in editor.

Quick checklist before final import

• Ensure consistent palette across assets.
• Trim and pack sprites into atlases.
• Verify pivot/origin points for animations.
• Test in-engine at target resolution and lighting.
