Check out this great tutorial by UI Designer Polat Yarisci.
Polat Yarisci, a UI Designer from Istanbul, has released a great tutorial on making a realistic plant using Cinema 4D and Octane Render. In this tutorial, Polat explains the scene, shows how to model all the different parts of the plant, goes deep into material creation, and demonstrates how to set up the interaction between the plant and light.
This is not the only tutorial made by the artist. Last year, Polat showed how to set up Volume Fog and Water in Octane and Cinema 4D. In that tutorial, the artist explained many things regarding Volume Mediums in Octane and how to use them to create water and foggy atmosphere.
