How to make dunes and change forest color ?

[psycraft]

The title says all. Using the world builder, i can't find the function for changing the color of forests (always green) and to have dunes instead of hills in desert hexs. As i could noticed in some downloaded maps it's possible so maybe it needs a specific tool/action outside the world builder ?

Thx, & sorry for my english.

you need to set the continent type (I think african is the type with dunes)
