The 3x3 grid technique for generating consistent game asset sets. Characters, environments, weapons, and logos that feel like they belong in the same universe.
The Key: 3D Printable Mindset#
Even if you're not 3D printing, thinking in physical forms produces cleaner results:
- NO glow effects, particles, or auras
- Solid physical forms only
- Surface details are sculpted/carved, not rendered
- Clean silhouettes that read as miniatures
Base Prompt Structure#
"Stylized collectible 3D-printable game asset 3x3 grid on pure white (#FFFFFF) seamless background. Asset set: [THEME], stylized hand-painted sculpt aesthetic, Supercell/Clash Royale inspiration, designed for 3D printing. Each asset centered in frame, identical 3/4 front view (30° horizontal, 15° down), no platform, no stand, no shadows, floating presentation, consistent scale across all 9."

- Holy paladin - golden armor, hammer, halo headpiece

- Swamp ruins - mossy stones, murky water, willow trees
- Desert oasis - palm trees, tent, golden sand dunes
- Volcanic forge - lava rivers, obsidian pillars, anvil
- Cloud temple - floating stones, rainbow bridge, wind chimes
Weapons#
- Fire sword - molten edge, ember core, heat shimmer sculpted
- Ice claymore - frozen blade, crystal hilt, frost patterns carved
- Lightning katana - crackling edge, storm cloud guard, bolt engravings
- Earth hammer - stone head, root-wrapped handle, gem inlays

Why This Works#
The constraint of "3D printable" forces the model to:
- Avoid transparency and glow effects
- Create solid, readable forms
- Maintain consistent lighting
- Think in physical space
Result: Assets that actually look like they belong in the same game.
