My first experiments with climate haven't been too successful...but that's ok. I refined experiments with altitudes/textures coming out of FT Pro and being fed into the layer masks for elevation/hills/mountains/peaks/ice. Here's where I'm at so far. Everything (except the one experiment with forests) is based on exports (repeatable for any map made there) from FT Pro and with changes only made using in-photoshop menu commands (repeatable).

Thanks again for sharing this excellent (and educational) tutorial.
