Balanced Lighting Tutorial

Using Lighting Channels you can easily balance the lighting of various sources to achieve the effect desired.

This model was provided by Boothy to demonstrate how lighting channels can be user.

Quick Notes:

1. You can set the names of the channels in either IRender nXt, (from the Lights tab), or in the Batch renderer (using the lightbulb icon)
2. However you must inform IRender nXt of which channels to use for which light sources, and how many channels to use before starting the rendering.

Samples

Extreme Samples Many of these samples have only one channel enabled so you can see just which lights are effected by which channel.
Original Rendering All channels set to the default intensity of 1.0	Balanced Lighting Other Lights - (lights outside door) and Self glow - (glowing panels on the wall) - made very intense (40.0) for effect and other lighting channels adjusted to achieve desired effect.
Nighttime - Sun and Sky turned off For an evening scene, we would probably leave the sun off, but add just a little sky.	Sun only No sky. Only the sun, and it reflection from objects in the model, illuminates the scene.
Daytime - Sun and Sky only No interior lights. Sky adjusted down, because at 1.0 it was too bright.	Other Lights only Lights outside of window were in channel Other Lights.
Selfglow only Illuminated panels on walls.	Recessed ceiling only The lights are not visible in this view, but do add the the overall lightin..
Uplighters only Lights above panels on walls.	Pendant Down only Down light from hanging pendants..
Pendant Up only Up light from hanging pendants..
Balanced - full image after 1,300 passes. (probably more than were needed, but I let it run all night.)
