Ok, I reduced the size of my texture to 512x512 (as kevinp indicate in his tutorial that the size of the mask cannot exceed 512x512), but ... same as before: few trees, but not where they are supposed to be.
Anyway, a little help is better than no help at all.

Thank you Stuka :wink:

You are welcome, as kevinp said the size is important as i see you named your textures as"fw_Country3_fields.tga andfw_Country3_fields.tree.tga"
but you have to move the word "fields" to the binging i.e you have to rename those like:
fields_fw_Country3.tga and fields_fw_Country3.tree.tga
test with 512x512 (1MB for texture) and 512x512 (256kb for your gray scale tree map texture) then you can experiment with 1024x1024.
good luck :wink:
