This isn't about what they'll look like, but where they'll be placed. I'm assuming they eventually won't only just be on the hills and slopes. Will they be everywhere (not including environments like deserts etc)? or will there be artificially generated (or.. not generated
) clearings? Will tree density (and artificial clearings etc) be only done by climate (with randomized density and clearings specific to that climate) or is there tree data more specific than just climates that you'll use?
