Gumroad – Group Pro v2.1.8

Features:

• edit any instances on scene (not just the ‘source’ one, like it works by default, with collection instances)
• work in recursive way – group, can be created from subgroups, which can be made of subgroups etc. Any
• subgroup can be edited and saved, with all other instances updated in real-time
• easy mirroring of selected groups (fixes group instance mirror bug in blender)
• change group origin, without destroying positions of other instances placed in scene
• apply transformations to group (location, rotation, scale)
• dissolve group (split it into original objects)
• ability to edit linked libraries groups directly in current blend file
• edit material in all group sub-objects in one click (replace, add, assign mat)
• create group proxies (temporary lowpoly version, to speed up viewport)

This makes working with huge scenes with lots of objects easy and gives all the pros of group instances:

• less memory memory usage
• easy selection of multiple objects with one click
