Indoor lighting

Indoor lighting can have different scenarios – the key light can be natural or artificial, and natural light can be direct (illuminating the scene with bouncing rays) or diffused in a Scandinavian style. Each of these scenarios has some variations. If you use path tracing, it is easier to achieve realistic lighting, as the light paths are physically accurate and correct and you don’t need many adjustments. However, if you use Lumen, you have to assist it and its indirect bounces more.

Natural light

The light system is generally the same as what we used for outdoor scenes, with one key difference – the indirect, bounced light. Especially with natural lighting, a key factor is indirect light – light bounces are what define the environment the most and what path tracing aims for. So, when you use path tracing, you don’t need to worry about the light bounces, as they are already physically correct. However, when you use Lumen, you...
