Learn how to balance indirect and bounce light.
- [Instructor] To put the finishing touches…on our practical interior day lighting shot,…we need to balance the suffuse illumination,…coming from the sky, with the…diffuse reflections, or bounce light.…We have some suffuse illumination already,…our back light here, which is an area light.…An area light is the recommended method…for representing the sky, in an…interior rendering, in Arnold.…The Arnold sky light is not recommended,…because there is no method to focus the computation…in through the narrow aperture of the window.…
And the Monte Carlo ray tracing engine…will produce a lot of grain, on the interior.…You need to use an area light, as I've done, here.…I've got one for the back light,…we'll also need one for a fill light.…Behind the camera, we're staging the effect…of direct sunlight, coming through…the panes of glass of a window.…We already have the sunlight, we also need…the suffuse illumination, coming from the sky.…Let's isolate our key, fill, and back lights…from one another, using the Intensity attribute.…
