This is for a client who's developed a new power drink, and needed an illustration. The bottle was tricky because TCAD failed to shell one large solid. I had to break the bottle into three sections, shell them, and then rejoin. Worked fine, took a while to figure out. The bottle is a custom material I use as clear plexiglas, which worked well in this application. Also learned a lot about cylindrical wrapping...! This is a screenshot of the rendering, in Lightworks, Softbox, and an accent light.
