Blender 2.90: More Features¶

Data Duplication¶

Data-blocks duplication (or deep copy, full copy) has been improved.

Doing a full copy of a scene will now use the same preference settings as when duplicating a collection or object, to determine which sub-data-blocks should also be copied (#77255, eee35ebdfb).
Doing a full copy of a scene or collection now duplicates actions only if relevant option is set in the user preferences.
All usages of duplicated sub-data-blocks should now be properly remapped to their copies.
Doing a full copy of a local data-block will now never duplicate the linked sub-data it may use (this was already the case for scenes, but not for objects or collections before).
- However, doing a full copy of a linked data-block will also duplicate all of its linked sub-data, if allowed (since user then wants to get a locale duplicate of its linked data).

New Ray Length setting, which limits how far rays can travel before they are excluded from the baking result. Useful for baking meshes with holes in them. (27cac4a102)

Added new lens distortion model which allows to solve motion in Blender and do compositing in Natron/Nuke. It is available in the Lens settings of movie clip and is called "Nuke" (which is the default model in Natron as well).

The User Preferences → Developers Extra → Experimental options are now organized in different categories (dd9c0dbf5e).
They are also only available on daily builds of master. Beta and Final releases don't have their panels.

Linux now has initial Wayland support, when building the WITH_GHOST_WAYLAND option. Some features are still missing in this implementation and X11 remains used by default for now.
