Finished this challenge. My computer is VERY slow though, so my rendering times were quite long, and I discovered that the estimate times were very inaccurate on my computer. Because of this, I have only recorded 2 render times for my CPU, because my computer won’t let me use my GPU for rendering. In fact, it wouldn’t let me install the driver update stuff because it wasn’t compatible with my computer. Rendering the simple cube took 23 seconds in cycles! I also have to stick to an older version of Blender (Version 2.74) because when I update it, it opens and crashes immediately because of my computer’s outdated graphics card, or something like that. However, I will be buying a new (better) computer in about 2-3 weeks, so this soon won’t be a problem anymore, and I will redo this challenge then. Anyway, here are the render times at the moment with my CPU rendering the images.
124x124: 1h 10m 39s
16x16: 1h 9m 25s
PS. I did make sure that I had no other tabs open (I even closed the udemy) so it wuld go as fast as possible.
