Density Target & Budget Enforcer

Quadify Premium provides two approaches to face count control: Density Target computes reduction from world-space surface area, and Topology Budget Enforcer hits an exact face count target.

Density Target

Density Target computes polygon reduction based on world-space surface area instead of a fixed ratio. This allows assets of different sizes to maintain consistent polygon density.

Quadify calculates the surface area of the object in world space and derives a reduction ratio from the target triangle density (tris/m²). Three one-click preset buttons remove guesswork:

• Game prop — 3,500 tris/m²
• Cinematic — 12,000 tris/m²
• Mobile — 1,200 tris/m²

If Density Target is disabled or cannot be computed, Quadify falls back to the standard reduction ratio.

Common issues:

• Very small objects may over-reduce if density is too low.
• Non-uniform scaling affects world-space calculations — apply scale before running.

Topology Budget Enforcer

The Topology Budget Enforcer decimates to an exact face count target using iterative convergence. It hits within ±2% tolerance (configurable), removing ratio guesswork for deliverables with hard face count requirements.

Found in: Reduction Settings. Enter a target face count and click Reduce to Target Count. The enforcer runs multiple passes, converging on the target from above to avoid going under.

When to use:

• Marketplace assets with published poly budgets
• Engine streaming LOD requirements
• Client deliverables specifying maximum triangle counts

Density Map Painting

Density Map Painting lets you paint a vertex color layer that controls where reduction is applied spatially. Dark areas reduce aggressively; light areas are preserved.

1. Click Create Layer in Reduction Settings — this creates the quadify_density vertex color layer initialised white (preserve everything).
2. Switch to Vertex Paint mode and paint dark where you want reduction to concentrate.
3. Return to Object Mode, enable Use Density Map, and click Reduce with Map.

Density Map Painting works alongside Density Target and Topology Budget Enforcer — the map modulates where the global reduction is applied rather than overriding the target.

When to use each

• Density Target — normalising a library of mixed-size props to a consistent visual density.
• Budget Enforcer — hitting a specific number, fast, without guessing at a ratio.
• Density Map — keeping detail where it matters (face topology, panel edges) while reducing aggressively on interior or occluded surfaces.
