Placement, Density & Masks

Which source should I use?

• Manual — exact hand-authored plants, hero flowers, special props and sparse composition.
• Density — broad painted coverage where the exact individual positions do not matter.
• Noise — deterministic procedural breakup and biome-like variation.
• Manual + Density + Noise — normal production workflow; the sources can coexist.

Placement masks

Painted Placement Mask suppresses rendering from each instance root without deleting the density/noise/manual source underneath. Use it for reversible visual exclusion over paths, buildings, water, props and clear zones.

Automatic placement masking can derive blocked areas from configured sprite/collider layers. Keep the layer selection narrow so unrelated scene objects do not become mask input.
