I know Grass in ENS is rather automatic.. but here are some I made.. I make small changes from project to project but those are nice base.. Specially if somebody starts now..
I attach some images, My Library of .skm materials.. and .skp 2016 file.. Library was saved in 2021 so not sure if everybody can read it..
Most materials are Doubled cos Not always I need a render .. most of times we need simple sketchy images in pastel colours.. So I made some materials Which in sKetchup look pastel but quite realistic in render..
material library 1 2 3 (separated cos of file size limit)
