yes I use Tree Druid Marque (sometimes in combo with Anything Grows, which is a great way to plant a more realistic forest)... in fact I often use some of Kromekat's stuff in the Marketplace here to texture them, I will post some screenshots here of my shader if you like :) the worst part is understanding how transparency works for leaves (how it works for everything really, transparency just isn't simple in Carrara)... but once you have that one down its really easy. (and by looking at a shader, you just can copy how it works anyway!)They have some help with shaders on the zenstar page too. Give me a bit, and I will post screenshots of my tree shader. also a tip, your poser figures have to be much bigger so they accept transparency well too. I realised there's a bug with that at small sizes.
