Balanced Lighting Tutorial
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:
- 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)
- 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.
