PROJECT FOUNDATION

Shape your project before you add traits

Canvas, groups, identities, and normalization choices stay explicit and local. Rename and reorder without changing project relationships.

Welcome to the Generator

Upload transparent PNG assets sized for the 256×256 project canvas into the layer groups on the left panel. Each layer represents a trait category — background, clothes, character, and accessory.

✨ Step 1: Upload your layers🎲 Step 2: Shuffle & preview🏷️ Step 3: Inspect traits

Source PNGs should match 256×256 pixels or use the explicit normalization choice above.

COMPATIBILITY

Rules & Valid Capacity

Rules constrain actual combinations before generation. REQUIRES is directional, EXCLUDES is symmetric, and ALLOWED WITH accepts any configured target in the same target group.

Valid combinationsBounded

WhenRuleTarget

The raw space exceeds the bounded solver budget. Reduce enabled traits before generation.

COLLECTION INTELLIGENCE

Collection Doctor

Catch collection problems before generation. Analysis is read-only, browser-local, and uses the canonical Creator selection solver.

WHAT · WHY · AFFECTS · ACTION

BLOCKERRequired group has no selectable asset

What is wrong?: Background has no enabled generation asset and does not allow None.
Why?: Every complete selection must choose one option from this group.
What does it affect?: Background
What can change?: Enable or import a generation asset, or make the group optional with explicit None semantics.

BLOCKERRequired group has no selectable asset

What is wrong?: Character has no enabled generation asset and does not allow None.
Why?: Every complete selection must choose one option from this group.
What does it affect?: Character
What can change?: Enable or import a generation asset, or make the group optional with explicit None semantics.

BLOCKERCollection has zero valid combinations

What is wrong?: No valid positive-weight complete selection exists.
Why?: The active group and compatibility rules eliminate every completion.
What does it affect?: Generation readiness and requested supply.
What can change?: Add compatible enabled traits, relax the conflicting rule, or explicitly allow None where appropriate.

BLOCKERRequested supply exceeds valid capacity

What is wrong?: The requested 10 items exceed 0 valid unique combinations.
Why?: Generation without replacement cannot produce more unique DNA values than valid capacity.
What does it affect?: Generation readiness.
What can change?: Reduce requested supply or increase valid capacity.

WARNINGRequested supply is close to capacity

What is wrong?: The requested supply consumes most valid unique combinations.
Why?: Deterministic uniqueness leaves little selection headroom near capacity.
What does it affect?: Generation flexibility and rarity distribution.
What can change?: Reduce supply or broaden compatible trait choices.
