Ok, I try once again:
If you take Istvan variant of Balaton you'll notice regions with lot of trees. If you investigate you find that those regions are midland0. If you look into load.ini you see:
midland0= fields_midland_ian.tga.
No I go to another map (it was Stalingrad) and paint midland0 somewhere and assign in load.ini
midland0= fields_midland_ian.tga
Scarcely any trees there. So what makes the difference?
Another point to consider: coming back to Istvan's Balaton variant there's also another region namely lowland1 also assigned to fields_midland_ian.tga. However for that region you see scarcely any tree. What makes the difference?
On all default maps as far as I know such density of trees appears only in regions filled with fieds1.tga or fields2.tga or autumn_fields1(Ithink).tga. Those are also the only files which have associated a x.tree.tga.
Please tell me more about this transparency, that's something which sounds chinese to me lol :?
Trees are so dear to me, please help solving this mistery
