I recently did a course for creating realistic plants (botanically correct) in SpeedTree( and soon GrowFX). I thought I'd share some of the final images with you.
A little about the scene :
Over 120 different species of plants was specially built just for this this scene from scratch, which include moss, grass, flowers, plants, ivies, vines and trees. I ended up using about 30 different species for the scene.
I did use both Corona and V-ray to render out images. There are more than 400 billion polygons in the scene via instancing (Using forest pack pro) and over 100 million unique polys. I also did use over 400 textures for the scene ranging from 0.5 k to 4k images.
Opacity is used for most leaves. All in all it took less than 8 hours to render the scene on an i7 4 core(8T) with 12GB of memory with over
60 render elements . (There are 2k and 4K renders)
Here's a link to the course if anyone is interested : http://shlece.com/product/the-art-of-landscaping-with-speedtree/
I'd appreciate any feedback
