******WARNING: GRASS (not trees) ARE INSTANCES so, it mays do not apear in others softwares than cinema4D.******
This cave have been made and textured with the software SCULPTRIS (free), grass and trees come from cinema4D and the render too. However, a copy of each kind of grass is present on the file (a copy incorporated of polygones) in order to clone it if need.
I also let you the sculptris file, if you wan to edit it. The TEX file contain: Wood texture Texmap of the cave Bumpmap of the cave Be careful, the project contain a lot of polygon, it may be that some pc does not support it. Unfortunately, sculptris texturer does not allow texmap more detail than 2k. That's why inside the cave, the texture is bad.
