Actually the tree is in "Pitch Black" part of the image map.

There is absolutely no grays areas in the map. When I get home, I can update the thread with image of actually map. It simple - drawer a small black line down the middle of 1024x1024 white square.

step #3 is very important in my test.

Everything works if I used the distribution map as underlying texture for the terrain. Only when I change it to use mix materials with a distribution map under it.

I have work around the isuse by always assuring that the ecosystems are done first but I should not have to do so. Is this possible, if my black is not 100% pitch black in rgb colors ( no where near gray ), could ecosystem be that sensitive. Does it have to be RGB(0,0,0)
