Here are the trees i made, their maps, and their poly count for my final assignment for 2D/3D class. I should and would have had more maps for them but when i was baking the AO map wasnt making that much difference, if any, on the texture or the model itself. For the height/ directional map it for some reason highlighted all the low poly edges with a feathered black and looked really bad.
ALBIZIA SAMAN Trees
COCONUT TREES
GOLDEN SHOWER TREES
Here's the main trees fully lit in maya.
