I use Warcraft No Limits its a tool u can download where u can place no limit of doodads, on this picture and on this work only i have only 16453 Doodads but it is not much for me comparing to my other maps. hehe Lt.
Looks awesome. May I ask you a question? How many doodads are used on this screen?! Because it looks like VERY many doodads have been used... I'm working on a map too now (yes, I must admit it's an Epic sized map), and I'm already at my doodad cap, altough I still have 1 4th of my map to do (and the rest aint that 'overloaded' with doodads either like this one...)
Maybe it only looks like it has much doodads because the trees are bigger than usual (?)
