Hi Andy thanks for this will certainly check it out. As a suggestion, another thing are materials (and their textures), which are not easily identifiable but are essentially redundant. These include the base mannequin his bp and asset relations, glass materials, some basic materials for basic coloring, which are part of many asset packs. However, usually it is enough to use a few glass materials, only one or two mannequins, and colors can also be shared. So what would be nice to make a list of the most common materials, textures, bp, to produce an overview list of them, and then you could decide which to delete and what “double” you would take as replacement file.
So this was just an idea I got when I read yesterday your comment in the other thread about deleting doubles. Not sure how feasible this is, but it is certainly something where you can reduce project file size, and make the project more manageable.
