We've just shipped v2 of the Procedural Placement Tool, and it's a massive upgrade. Here's what's new.

Biome Zones

The biggest addition is the biome zone system. You can now define distinct biomes — forest, desert, wetland, urban — each with its own placement rules, actor pools, and density settings.

Biomes blend smoothly at their boundaries, so you won't see harsh transitions between regions.

Density Painting

Paint density maps directly in the viewport. Instead of tweaking numbers in a spreadsheet, you can brush placement density onto your landscape in real time.

The density brush supports:

• Additive and subtractive modes for fine control
• Configurable falloff curves for natural-looking transitions
• Per-layer painting so each actor type has independent density

Performance

v2 is significantly faster than v1:

• Placement calculations are now multi-threaded
• We added spatial hashing for collision avoidance
• Preview rendering uses instanced static meshes instead of individual actors

On our test landscape (8km²), full regeneration dropped from 12 seconds to under 2 seconds.

Upgrading

If you already own v1, the update is free. Check the getting started guide for migration steps.
