Lightgen

The lightgen script is designed to work with Softimage XSI to generate a rig of lights from HDR image data. A plugin for HDRShop is used to generate the data in simple text file format from the original HDR image.

The script is an extension of the original script by Robert Ryan. The original script, although fully functional, didn't give much control (other than XSI's ability to manually edit each light individually). This script adds two panels of controls.

The first to control the different banks of lights (intensity multiplier, shadows, GI, area lights etc).

The second panel controls coloured cubes indicating the position and colour of each light. This allows very quick alignment of the light-rig to a 3D environment.
