Thank you! I know This was more like a test to see if all the plants work correctly. Plus, if you look closely, some of the plants show up inside the tent, also need to be fixed.
For the plants I used these models: http://www.vizpark.com/shop/real-grass/
They are meant for 3DS Max but if you want to use them in SketchUp with Skatter, it takes a lot of time to export/import as VRAY proxies and remap the textures. Real quality models. Cheers!
