Biome Layers

Overview

Biome Layers allow you to specify where biomes should be applied to your terrain. They also offer sculpting functionality, enabling you to paint your biome onto your terrain while simultaneously modifying the base terrain. This creates a much smoother application process, providing instant feedback on the final result.
