basically, when applying these shaders, you have to use the those blue pulldown menus and choose the right options you see here. (I think you know that, but not sure, so I'm getting basic there) From the top, you have to choose the Layers list, that way you get the option to use Parametric mapping and can see all the materials that are defined already in the trees that Tree Druid generates. No need to uvmap them, they are uvmapped already and easy to texture. :) Layers list will give you those little "plus" + signs at the bottom of each material, click on that plus sign in the Leaves material to get the Cover all Layer option to make the transparency mask for leaves that you see here. I save these shaders to my library of shaders too, so I can easily reuse them on other trees. :) You do that by dragging the top of the shader and dropping into the left side library where you see the shaders (just make a directory for your own shaders there)and apply by dragging the shader onto the tree shader you want to shade. If you are doing this with multiple instances of trees used as tip objects, apply your shader to the plane or object that is using Anything Grows, it will then shade the tip object trees perfectly. (I hide the anything grows terrain or plane then, so you can't see that part anymore.) I'm almost done with a render using some of these tips, that I will post. I got the idea of using Anything Grows to easily make multiple trees for forest when I saw a Lightwave tutorial in a magazine to do a similar thing with a hair plugin to create natural scenery. Works GREAT in Carrara too!
