Largely responsible for the nice shape of the canyon's displacements and appearance are two files: namely, FrankB's 'Wavy Terraces Surface Layer' file and dandelO's '10m Cracks' file; both of which transform the 'strata and outcrops' rather well. Also, dandelO's PGS -Evolution file for procedural grass was used as a green base for which many of the vegetation models would appear. Files available at the Planetside Forum.
Finally, three populations of model bushes were used. two of which were created by Walli (#7 AND #8). The third is a leafless bush - sorry, I do not remember the creator. Our symbol of freedom and strength - The Bald Eagle - model; thanks to Mark. Walli's Dry Shrubs available at NWDA.
This will be enough of canyons for awhile ...on to another, different project.
