and here is the first testrender that shows a part of the canyon I build right now with some stuff from my content.
for the backround I have used predatrons backround from droping rocks with a fixed texture from this set plus some deformers for more profile (for the little pond on the left for example and for the sides of the canyon you not really see here clear but without the deformers the backround would look different)
for the bolders I have used some from first bastion with the fixed texture from predatron so they fit to the canyonbackround
for the water I have used water from flinks water set
the trees are the tall pine trees from forest tree - tall pine and from the forest set (fallen pines) by andrey pestryakov
the bushes are the dead bushes from lisa`s botanicals - dead bushes
the light just for this render is just one distant light with shadow softness 3% and white color intensity 100%
contrast I have fixed a bit in postwork but just a bit.
