In this course we will cover the essential techniques of rendering in Blender using Cycles. For those of you who new to Blender, Cycles is a rendering engine that is comparable to V-Ray, Corona, Arnold, Octane etc. Essentially Cycles can simulate real world lighting condition, so it enables us to produce photorealistic images. But unlike the other rendering engines, Cycles comes bundled with Blender so it is free and you don’t need to download or install anything separately. Basically if you use Blender then you already have Cycles.
