I uploaded another revision of the maple tree that has no scanned image of a leaf painted on the leaves. The notable change was on the form of the leaves and their arrangement. The leaves are now curving in two directions. Their positions on the twigs had been re-arranged in a way that those on the tips would be a bit smaller and do not block the leaves behind them. This model is included in the 3d tree collection in the 3d warehouse.
The images below show a comparison between the revised maple tree and the Maple tree (very detailed) revision 1. The first one shows the model mentioned in this post while the other shows the version which still has the leaf images painted on the leaves. Both images are rendered in Indigo Renderer.
