BlenDiff：Blender 工作流工具插件

BlenDiff shows what changed between two versions of a .blend file, in terms of the scene rather than bytes.

Save a named snapshot at any point. Snapshots are stored in a .blendiff file next to your .blend, so a project directory holds only those two files. Compare any snapshot against the current scene, or against another snapshot, and see which objects were added, removed, renamed or modified, down to the individual property.

What it compares:

• Object transforms, visibility, parenting and custom properties
• Mesh geometry, through content hashes that catch a moved vertex, a re-subdivided surface or a re-unwrap without storing the mesh itself
• Armature rest pose and bone hierarchy, including roll and connection
• Materials and their node graphs, world and render settings
• Collection membership, modifier and constraint stacks, animation F-curves, drivers and NLA tracks

Renames are tracked as renames rather than a delete plus an add, using a persistent id stamped on each object, so history survives renaming and reopening the file.

Three-way merge takes a common ancestor snapshot and two divergent versions, applies the changes that do not overlap, and asks you to decide the ones that do. Transforms, visibility, parenting, custom properties, collection membership and render settings are written back for you. Constraints, modifier stacks, drivers, NLA tracks and material node graphs are reported with the reason they need reconciling by hand rather than being applied silently.

Diff results can be exported as a self-contained HTML report to share with people who do not have the file open.

BlenDiff makes no network connections and reads or writes nothing outside your .blend's own folder and the report location you choose.
