Umbrella tree model was made by me in 2005 in 3ds max 7. No plugins were used. I Have rearranged the scene for 2011 now.3ds Max. OBJ and FBX included. Only two textures were used. The model comes in two slightly different versions. The model is lightweight and perfect for environmental renderings. I left the scene with Standard materials, so you will have to convert to Vray materials up to your taste.
