In Blender 2.8, we have introduced the concept of Collections to replace the old layers system.
This is much more powerful:
- At allows naming
- You can have more than 20 layers
- Collections can be nested
Users can set up their Collections in the Outliner. They can name them, structure them and organise them there.
However, we are also considering a way to access Collections directly in the 3D View. In Blender 2.7 and earlier, the 3D View header had a layer palette:
The problem is that this is no longer a good fit, for these reasons:
- It doesn't communicate the name
- It only allows for 20 layers
- It doesn't allow for communicating nesting
- It's a completely different mental model
For these reasons, we don't want to re-use that interface in Blender 2.8.
Instead, we will provide a panel in the N-key area, with a list of nested collections with their respective names, like so:
This will allow users to show/hide or solo collections.
For now, we probably won't allow renaming or re-ordering here. This is just a quick way to show/hide collections.
