Hi all, first...is a wonderful map, a good work. very nice. but trying to upgrade the trees I copy/paste the FIELDS lines and, change the forest setting to =3, but I only get this. I think that is all you say to do it.
Something like these colours, maybe not so bright.
Not many evergreens would be seen around fields
a few Holly bushes maybe, but some pines would be in forests.
Some trees will stay green quite late like Oak.
