I’ve published a new free tutorial:
How to create light layers in Blenders compositor
In my example “light layers” are actually rendered images of all light sources in a 3D scene. Every rendering is representing a single light object, a light group or a complete world lighting. This technique is similar to light mixing techniques you may know from other software.
The final rendered results will be used in Blenders compositor to control their light intensity and color. All your lighting adjustments will be updated in about real time. And because every image is already in high quality, there is no need to rerender the whole scene when changing the light intensity. And the very best: you can do this even for complete frame sets or animate the light values, if needed. This can be a real time saver!
This video is for compositing newbies, intermediate users and all who are interested in this technique.
