Blender Light Paint using Spherical Harmonics

by Jingyuan Huang for Blender Foundation

Inspired by Illumination Brush, this project aims to create an interactive tool for Blender to preview, modify, and create image-based lighting environments specified by HDR light probe images. Artists can change the HDR light probe by directly painting colours on the models. This tool will be integrated with the existing image-based rendering routines in Blender in order to help artists determine the final renderings.
