Control distance intensity with a Light Decay filter

“

- [Instructor] Another way to improve interior sampling quality and reduce render times is to use area lights instead of a sky dome and that's what I've done in this scene. I've placed area lights over all of the windows and doors. This method of representing environmental illumination also gives us more control over the look of the light 'cause we have the area light parameters such as color and spread whereas we don't have those controls with a sky dome. However, area lights outside the windows can actually over expose the window frames and any nearby geometry but in this movie we'll get around that. We'll use an Arnold decay filter modifier to compensate. Let's do a baseline rendering of what this would look like with an ordinary sky dome. I've got that placed in the scene and let's do a production rendering of our master shot. When that concludes, we can see that we're getting an even illumination. There's no actual…
