A very important aspect in daily production, is to keep assets organized and easily accessible. We needed some system to link complex environments into a scene and being able to toggle the visibility and complexity or their components.
With the vital contribution of Olivier Amrein (oenvoyage) we realized an addon called Powerlib, that allows toggling visibility and level of detail (high and low resolution) of subgroups contained in a linked group.
You can download the addon from a github repository (and also help us improve it! There are a few features that would be nice to have:)
