C4D Plastic Materials Test

Here's a test render I created yesterday. I was most interested in learning about creating clear plastic/glass materials in C4D. I found a very helpful tutorial on Grayscalegorilla.com which taught me the key to this look is in the transparency/reflectance channels of the clear tube, and of course good lighting and HDR. A personal goal I have is to create a few images like this per week, based on tutorials or not, and include some text that give me a "recipe" to look back on if I ever want to revisit it again in the future.
