I'm not sure how long it took to render, not that long though. I'm creating a project that has the leaf emitter model and a basic tree model to use with Treez plug-in v.3. I found a way to transfer the hair material to the tree model without losing the sliders for the hair. It will include leaf and bark images. If people are interested I will create a folder with project, images, 2 models, the treez plug-in file and a text file with instructions on how it all works. I'm still working on gathering images and attempting to add a second emitter to add more density or to add flowers or fruit to the tree. I found a couple of problems with the first model that if you add it to the tree branches they take on the color of the material, if the tree is not decaled (v.3 treez plug-in decals tree). The second is if you add it to a group that is not attach to the tree the same happens. You need to set the transparency to 100% on the group and 0% to the material. Now back to finding more images.
