Description - Birch modeled using GrowFX plugin. Snow SnowFlow generated by the script. In the archive file that you saved for 3DS MAX 2013, but since I have not installed, check could only version for 2014, opened with no problems. Also there is an OBJ file format. In stage 3 types of birch: Summer - with green leaves. Autumn - with a bit of a reduced amount of leaves and the foliage itself, of course yellow Winter - absolutely bare tree covered with snow. Material collected through the foliage blend material that is in any time can be made of green foliage, converted into yellow, by switching the material in the blend. In the scene, there are 2 types of materials, the basic yet the Corona, as I work in it, the Vray more additional, I have not been working in it, not a lot of skills.
