user: Give a detailed overview of Recovering an Auto Save: syntax, arguments, return values, common patterns.

assistant: Blender automatically saves temporary backups of your work at regular intervals.
If Blender crashes or you close it without saving, you may be able to recover your work using the autosave.

Follow these steps to recover an autosave:

1. Open Blender.
2. Go to the top-left menu bar and select: [File –> Recover –> Auto Save](../files/blend/open_save.xhtml#bpy-ops-wm-recover-auto-save).
3. In the file browser that appears, find the desired auto save.
   The files are named like: `<filename>_autosave.blend`
   Note, these files are timestamped to help identify the correct one.
4. Select the autosave file and click *Open*.
5. Once opened, immediately save the file manually using
   [Save As](../files/blend/open_save.xhtml#bpy-ops-wm-save-as-mainfile) to avoid overwriting the autosave.
user: Explain Space in complete detail according to the official Blender documentation.

assistant: While object positions, vertex locations are not clamped, larger values become increasingly imprecise.
To get an idea of the precision you can work with using different scales.
Here’s a table of scales and their associated accuracy:

10:
:   1/1,048,576th

100:
:   1/131,072th

1,000:
:   1/16,384th

10,000:
:   1/1,024th

100,000:
:   1/128th

1,000,000:
:   1/16th
user: Give a detailed overview of Copy/Paste: syntax, arguments, return values, common patterns.

assistant: Allows copying and pasting images between Blender and the operating system’s clipboard.

Note, only PNG files are supported for direct clipboard copying and pasting.

Platform specific behavior:

- Windows: Supports pasting images by copying the image’s file path. This method allows all supported image formats.
- Linux: Requires Wayland for clipboard image support.
user: What is Grease Pencil and how is it used in Blender Python scripting?

assistant: These overlays are available when a [Grease Pencil](../../../grease_pencil/index.xhtml) object is selected.

Onion Skin
:   Show ghosts of the keyframes before and after the current frame.
    If [Multiframe](../../../grease_pencil/multiframe.xhtml) is enabled,
    ghosts of the selected keyframes are shown instead.
    See [Onion Skinning](../../../grease_pencil/properties/onion_skinning.xhtml).

Active Object Only
:   Show only the onion skins of the active object.

Fade Inactive Layers
:   Decrease the opacity of all the layers in the object other than the active one.
    The opacity factor can be controlled with the slider.

Fade Inactive Objects
:   Cover all of the viewport except the active Grease Pencil object with a full color layer to improve visibility
    while drawing over complex scenes.

    Fade Grease Pencil Objects
    :   Include or exclude Grease Pencil objects.

Edit Lines Edit, Sculpt, Weight Paint, or Vertex Paint Modes `Shift`-`Q`
:   Shows a line between points on top of other geometry when editing strokes.

Only in Multiframe `Shift`-`Alt`-`Q`
:   When Multiframe is enabled and keyframes other than the current frame are selected,
    strokes on those keyframes are displayed as just their edit lines – the strokes themselves are hidden.
    Note that this does not affect Onion Skinning.

Handles
:   Controls the visibility of Bézier curve handles in edit mode.

    None:
    :   Hides all Bézier curve handles, providing an unobstructed view of the curve.

    Selected:
    :   Displays the handles only for selected control points.

    All:
    :   Displays the handles for all control points in the curve.

Stroke Direction Edit
:   Toggle the display of the selected strokes’ start points (green) and end points (red) to visualize their direction.

Material Name Edit
:   Show material name next to the selected strokes.

Vertex Paint

Vertex Paint Opacity Vertex Paint
:   The opacity of the vertex color overlay in Vertex Paint Mode and Draw Mode.
    Note that in Draw Mode, vertex paint is only visible in the *Material Preview*
    and *Rendered* shading modes by default. To see it in *Solid* mode, you either
    need to use Vertex Paint Mode, or set the [Color](../../../render/workbench/color.xhtml)
    shading setting to *Attribute*.

### Canvas

Display a grid over the Grease Pencil drawing plane.

Canvas Grid Opacity
:   The opacity of the grid.

Canvas X-Ray
:   Objects are drawn behind the canvas grid.

Subdivisions
:   The number of subdivisions between grid lines.

Grid Color
:   The color of the grid lines.

Scale X/Y
:   The horizontal/vertical size of the grid.

Offset X/Y
:   The amount to shift the grid up/down and left/right.

user: How do I use Animation in Blender? Include parameters, examples, warnings and best practices.

assistant: # Animation

The *Animation* section lets you manage settings related to [Animation](../../animation/index.xhtml).
This includes how editors look and also some different tools properties.

[image reference removed]

Blender Preferences Animation section.
user: Provide the full official documentation entry for Fill Between Joints, preserving all code examples.

assistant: # Fill Between Joints

The main use of this tool is to create one bone between two selected joints by pressing
`F`, similar to how in mesh editing you can “create edges/faces”.

If you have one root and one tip selected, the new bone:

- Will have the root placed on the selected tip.
- Will have the tip placed on the selected root.
- Will be parented and connected to the bone owning the selected tip.

Fill between a tip and a root.

|  |  |
| --- | --- |
| ../../../../_images/animation_armatures_bones_editing_fill-between-joints_example-1.png   Active tip on the left. | ../../../../_images/animation_armatures_bones_editing_fill-between-joints_example-2.png   Active tip on the right. |

If you have two tips selected, the new bone:

- Will have the root placed on the selected tip closest to the 3D cursor.
- Will have the tip placed on the other selected tip.
- Will be parented and connected to the bone owning the tip used as the new bone’s root.

Fill between tips.

| ../../../../_images/animation_armatures_bones_editing_fill-between-joints_example-3.png   3D cursor on the left. | ../../../../_images/animation_armatures_bones_editing_fill-between-joints_example-4.png   3D cursor on the right. |

If you have two roots selected, you will face a small problem due to the event system in
Blender not updating the interface in real-time.

When clicking `F`, similar to the previous case, you will see a new bone:

- With the root placed on the selected root closest to the 3D cursor.
- With the tip placed on the other selected root.
- Parented and connected to the bone owning the root used as the new bone’s root.

If you try to move the new bone, Blender will update the interface and you will see
that the new bone’s root moves to the tip of the parent bone.

Fill between roots.

|  |  |
| --- | --- |
| ../../../../_images/animation_armatures_bones_editing_fill-between-joints_example-5.png   Before UI update (3D cursor on the left). | ../../../../_images/animation_armatures_bones_editing_fill-between-joints_example-6.png   After UI update, correct visualization. |

Clicking `F` with only one bone joint selected will create a bone from the selected
joint to the 3D cursor position, and it will not parent it to any bone in the armature.

Fill with only one bone joint selected.

|  |  |
| --- | --- |
| ../../../../_images/animation_armatures_bones_editing_fill-between-joints_example-7.png   Fill with only one tip selected. | ../../../../_images/animation_armatures_bones_editing_fill-between-joints_example-8.png   Fill with only one root selected. |

You will get an error when:

- Trying to fill two joints of the same bone.
- Trying to fill more than two bone joints.
user: What is Render and how is it used in Blender Python scripting?

assistant: SMAA Threshold
:   Threshold for the edge detection algorithm used to correct aliasing for the final render,
    Higher values may result in loss of detail due to excessive blurring.

SSAA Samples
:   Number of samples used for super-sampling anti-aliasing in the final render.
    Higher values produce smoother lines but increase render time.

Motion Blur Steps
:   Controls accuracy of [motion blur](../../../glossary/index.xhtml#term-Motion-Blur), more steps result in longer render time.
    Only used when [Motion Blur](../../cycles/render_settings/motion_blur.xhtml#bpy-types-rendersettings-use-motion-blur) is enabled.
    Set to 0 to disable motion blur for Grease Pencil objects.
