With794c2828af&f48a4aa0f9it's possible to reuse possibly expensive, nested data of a data-block when appending. E.g. the texture of a material, or the mesh of an object. Without this it's easy to bloat memory and the file size. Duplicated textures also cause unnecessary shader recompilations. The feature was intended to be the new default behavior for the Asset Browser, but it wasn't actually added to the UI yet. This patch adds a new import type option to the Asset Browser. So from the menu in the header, you can now choose between: * Link * Append * Append (Reuse Data) The latter is the new default.
