Lesson 4 homework. First I planned to do this part with keyshot but eventually I decided to give the free tier Octane for Blender another try. This time it worked like a charm.
I noticed that with the same shader settings my renders were looked not so great. After that I figured out that blender filmic color correction is ruining my renders.
Turning on the post processing was also a bit unintuitive but after these minor inconveniences It worked very well. I really like this renderer It's very fast even with one GPU and the glow effect is simply beautiful.
