Character artist Daniel Bystedt shared Bystedt’s Blender Baker, a cool add-on that will help you save time on baking PBR texture maps and lighting in Blender. Free of charge!
The free tool makes it easier and quicker to bake data from high-resolution models to use with low-res versions in games and real-time projects. The toolkit allows setting up normal, displacement and ambient occlusion layers, plus Metallic, Roughness and Glossy.
What is more, it supports Channel Transfer letting artists mix individual RGB colour channels from different map types as a single packed texture.
