As a side note, I would suggest getting Onyx Tree for making trees. Especially if you want a hi-poly version for MXS and then export a very low poly version for SKP or even better, it will export shaded TGA which you can turn into a PNG file to save even more memory in SU. Using the new MXS reference feature it kicks serious butt. The Onyx program, although it looks dated is very powerful, will let you create tons of custom trees and shrubs and they export in 3DS, OBJ, FBX and other formats. Well worth the money. I think it was like $150 for the Broadleaf program and I feel like I have already created well over $150 in tree models. Highly recommended for sure for all SketchUpers.
