we have just try out our first

Many thanks for any constructive improvement suggestions, tips&tricks

This is what we did:
Take a ready-to-use model and placed some trees (with tree[d]) in 3ds Max
Make grass with Pflow and Mesh baker script in 3ds Max
Put materials in octanerender and make the settings
Set a background in Photoshop (ok, we know this is a very bad one. Anyone an idea where to get good background images?)
Render time with pathtracing setting: 1:30h
Resolution: 1600x800px
