New to the forums. I’m using World Builder and am fascinated by the use of programmatic noise and the procedural aspect of building worlds. Great stuff. I’ve search the forums a bit and read some stuff but haven’t found an answer to the following. Forgive me if there’s a thread out there that I missed.
I don’t completely understand the concept of a biome. I mean, I know what a biome is, but I’m not understanding how it’s used in the World Builder. Are biomes altitude-based (height-based). Do they describe 2D or 3D areas in the world which are affected by specific temperature and humidity values? Both?
I think I understand why one would provide a 2D noise pattern for vegetation, humidity and temperature biomes. Different objects (vegetation, etc.) can be populated in the world based on constraints in those various biomes. For example, only render this specific type of bush where the humidity biome has a certain value, or is within a certain range, etc.
But can someone explain why we would provide a 2D noise pattern (translated to 3D) for Altitude?
