Make the white dots bigger, at least six pixels to be sure of getting a tree.

The Tree map is a bit like the game Battleships, a tree won't appear unless your white dot hits it. You either need to make the dots bigger or move them about until you hit a tree. The smallest size for a dot is two pixels.

Thanks ... I was copying the way other such tree.tga files were made and the one I used as an example only had 1 pixel sized dots ... I'll try it with bigger dots ...

And set the forest setting at the highest setting as well ....
