The package will be for sale. Why should I move the thread to the developer forum, the package is developed to work only with Poser? Yes, those trees are fully 3D. Actually the trees are Poser pp2 files (props). You can plant any prop on the terrain with propgator. There are 51 props included in this package. You can use these or other props. The terrain is 256X256 vertices. I don't know how many faces... The package requires 80 MB free space and 512 MB RAM. Yes, the presets are salable individually. You can sell or distribute shaders, texture tiles, heightmaps (as 256X256 greyscale jpegs or Terragen RAW files), props. A heightmap can be exported as a morph target for the terrain figure ( an obj morph target takes like 2 MB of disk space). There will be free updates and tools to take advantage of the advanced material properties from Poser5 (like coloured detail textures), and 3DSMAX. The terrain's dimensions are 150X150 Poser units.
