I found a nice ''lawn'' freebie by Mike Vogelsang on SCG, albeit for DS.

But, totally wild poly-count. Then, converted to a bloated OBJ with DSF toolbox, it choked my CAD_Tower''s 3D viewers and PoserPro.
So, I exported the very nice material PNG to grey-scale with free IrfanView, applied that and material to Poser ground plane as bump-map and texture. Misreading displacement scale units, my first render lost LaFemme into wavy sea of ''Elephant Grass''...
Hmm. I wonder where I can find a free ''Howdah''...
