Many forest like biomes have such a high tree density, that no passive/neutral mobs are allowed to spawn, due to not being able to see the sky or a too dark light level.

Could you add a config value per biome to control the tree density , e.g. a percentage value for 100 being default.

Thanks for all the efforts you put into this mod.
