Your pyramid is amazing! The lighting is so beautiful, how did you do it?
The light i made by creating a spot light, with a big angel, and emission with a slight yellowish color, with a strenght of 50000. the orangy light in the pyramid is just a regular lamp with orange light emitting. and the sky i just added sky texture in world node. Notice that i am using the Cycles Render and not the Default Blender Render. I am Using my GPU to render.
When using cycles render it can show some firefly artifacts, usually this can easily be removed by doing one or more of these things on this link. https://www.blenderguru.com/articles/7-ways-get-rid-fireflies
Often it is fixed by setting the sample render to a higher value.
I hope this was somewhat helpful to you, and i think they are going to talk about lighting later in the course.
You are so great. I don’t really get it much now but I feel that when I learn more about blender this will be very useful to me. Thank you very much. I hope you have a nice day
