Interior light setup tips for Blender and YafaRay

The light setup is a very important part of any architectural visualization project, and I get a lot of questions about how to properly setup the lights for different kinds of environments. You may remember an interview I did with an artist called Stanislav Pyadishev, which uses Blender and YafaRay to create some amazing images for architecture. If you want to learn a bit about his light setup technique, he just posted on the YafaRay user forums a file that might help us to understand how he achieves a realistic aspect for interior scenes.

The file contains a scene without any piece of furniture, and all lights untouched. So, you can download it and open the scene to learn how he manages to get a realistic light setup. Just remember that the file was created with Blender 2.49.
