Recently I created a coke bottle scene, which is not exactly finished yet, but pretty close. Modeled in blender 2.56 and rendered in Luxrender 0.71. I’m attaching just one of the multiple renders here.
You can follow the progress of this project on this Luxrender forum thread. Also, for more details regarding the setup and materials, you can view my blog.
May I say I really love blender and Luxrender?
