![[Unity] Procedural Planets (E06: simple biomes)](https://i.ytimg.com/vi/Nxr0z6zKhOI/hqdefault.jpg "[Unity] Procedural Planets (E06: simple biomes)
In this episode we add simple colour biomes to the planet.

Note:
Two issues have been pointed out which Id like to address: (will add these fixes at end of next video)
1) changing resolution causes uv out of bounds error. This can be fixed by checking mesh.uv.Length uv.Length before assigning the uvs in ConstructMesh method.
2) biome colours appearing in wrong places when zoomed out (on certain devices). To fix this, mipmaps need to be disabled on the planet texture. In the ColourGenerator, replace with:
texture = new Texture2D(textureResolution, settings.biomeColourSettings.biomes.Length, TextureFormat.RGBA32, false);
