is there any tutorial on how to make a Sky Map
or some equiangular map
may be some HDRI Map
I need like an angular map with sky and ground
and in the background some trees like spruce - Pine - Fir
and at bottom some low level ground with small shrubs
I need to add some archi buildings in front of the background forest
and has to be at least photo realist
I did find one with normal trees with leaves !
but nothing so far with green trees!
any help appreciated
