A JSON file will be created in this folder for each skeleton in your project. The name of the file will use the name of the skeleton.

The JSON files will use this file extension.

Spine can optionally write in JSON-like formats that are slightly smaller, easier to read, and easier to edit.

• JSON Standard JSON.
• JavaScript Like JSON, but names are only quoted if necessary. The data is valid JavaScript.
• Minimal Like JSON, but most names and values are not quoted. This format requires a lenient JSON parser, such as the one in libgdx.

When checked, the JSON is formatted to be more easily read by humans. This makes the file slightly larger.

If an older JSON version is chosen, Spine attempts to write data compatible with that older version of the Spine Runtimes. In many cases this is not possible, data will be lost, and warnings will be shown.

Exporting to older versions is intended only as a last resort to partially recover work when a project was accidentally saved with a newer version of Spine. See recovering work for more information.

When checked, additional data is included in the JSON that is not usually needed at runtime. This makes the file slightly larger. This data is used if the JSON is imported back into Spine. See import for more information.

When checked, animation clean up is performed for the exported data. This does not modify the project file.

When checked, Spine will show any warning messages after exporting.

When checked, a texture atlas is packed during the data export. See packing during data export for more information.

A binary file will be created in this folder for each skeleton in your project. The name of the file will use the name of the skeleton.

The binary files will use this file extension.

The maximum number of colors in the GIF.

The amount of dither to apply to the GIF colors. Dither disperses the colors to prevent hard edges in gradients.

Alpha values below this value are treated as 0.

The amount of dither to apply to the GIF transparency. Dither disperses transparency to prevent hard edges. The type of dispersion and how the alpha range is used can be chosen for the best results.

The background color to use.

When checked, completely transparent pixels will be transparent instead of the background color. When unchecked, the specified color is used for the background of the GIF.

Translucent pixels are made opaque using the matte color.

Higher quality produces better colors but takes longer to export.

The number of frames per second for the GIF animation. 50 generally provides the best results.

When checked, the animation is looped continuously.

When unchecked, the last frame of each animation is omitted. Unchecking this is useful for looping animations where the first and last frame are identical -- the same frame would be exported twice when this setting is checked.

The background color to use.

Higher compression produces smaller files but takes longer to export.

The number of frames per second for the PNG sequence.

When unchecked, the last frame of each animation is omitted. Unchecking this is useful for looping animations where the first and last frame are identical -- the same frame would be exported twice when this setting is checked.

When checked, the exported images are packed into a texture atlas. This is convenient but running the texture packer separately provides more control over the packing. See texture packing for more information.

The background color to use.

When checked, the background of the APNG is set to transparent.

Higher compression produces smaller files but takes longer to export.

The number of frames per second for the PNG sequence.

When checked, the animation is looped continuously.

When unchecked, the last frame of each animation is omitted. Unchecking this is useful for looping animations where the first and last frame are identical -- the same frame would be exported twice when this setting is checked.

The background color to use.

When checked, the background of the images within the PSD is set to transparent.

The type of compression to use to create the PSD.

• RAW An uncompressed format. Encoding is fast but the exported PSD is very large.
• RLE Encoding is fast and the exported PSD is small.
• ZLIB Encoding is slow and the exported PSD is very small.

The number of frames per second for the PSD image sequence.

When unchecked, the last frame of each animation is omitted. Unchecking this is useful for looping animations where the first and last frame are identical -- the same frame would be exported twice when this setting is checked.

The background color to use.

Higher quality produces better images but the file sizes are larger.

The number of frames per second for the JPEG sequence.

When unchecked, the last frame of each animation is omitted. Unchecking this is useful for looping animations where the first and last frame are identical -- the same frame would be exported twice when this setting is checked.

The codec to use to encode the AVI video.

The background color to use.

Higher compression produces smaller files but takes longer to export.

For the JPEG-based codec, higher quality produces better images but the file sizes are larger.

The number of frames per second for the AVI video.

When checked, the animation is looped continuously.

When unchecked, the last frame of each animation is omitted. Unchecking this is useful for looping animations where the first and last frame are identical -- the same frame would be exported twice when this setting is checked.

The codec to use to encode the MOV video.

The background color to use.

When checked, the background of the MOV video is set to transparent.

Higher compression produces smaller files but takes longer to export.

For the JPEG-based encoding, higher quality produces better images but the file sizes are larger.

The number of frames per second for the MOV video.

When checked, the animation is looped continuously.

When unchecked, the last frame of each animation is omitted. Unchecking this is useful for looping animations where the first and last frame are identical -- the same frame would be exported twice when this setting is checked.

Resets all the export settings to the defaults.

Opens the preview panel for the export dialog.

Either animations or the current skeleton pose are exported.

All skeletons are rendered together in the same export, in separate exports, or only the chosen skeleton is exported.

The current animation, all the animations, or the chosen animation is exported.

The currently visible skins, all the skins, or all skins plus the skeleton without any skin active are exported.

Either creates a single file, a file per frame, a file per animation, a single file with multiple layers, or a single file with one frame.

The file to write (when a single file is exported).

The folder where files will be written, including the beginning of the file name for each file (when multiple files are exported).

The folder where files will be written (when multiple files are exported).

When checked, each exported file will have the same dimensions.

The number of times to play each animation.

The number of seconds to pause after playing each animation.

When checked, skeleton bones will be rendered.

When checked, skeleton mesh and region attachments will be rendered.

When checked, other skeleton attachments will be rendered.

Controls how much smoothing is applied to the image. Smoothing is a way of blurring the image to hide the pixel structure when upscaling, meaning when images are displayed larger than their actual size.

• 0 disables smoothing, nearest neighbor filtering is used. This can be useful for pixel art.
• 1-10 uses linear filtering between 10% and 100%.
• 11 uses bicubic filtering. This may be sharper and preserve details slightly better than linear filtering.

When smoothing is greater than zero, exports are affected by the Anisotropic filtering checkbox in the Viewport section of the Spine settings. Enabling anisotropic filtering may improve export quality.

The number of samples for multisample anti-aliasing (MSAA). See hull edges.

When checked, the specified bounds are exported rather than using the skeleton's bounds. The first two numbers are X and Y world coordinates. The next two numbers are the width and height of the area to export. When enabled, the bounds can be adjusted by dragging the orange corners in the preview panel.

The type of resizing to perform.

The relative scale of the image as a percentage.

When selected, the output image will fit within the specified pixel values.

When checked and the image is smaller than the specified size, the image is proportionally stretched until one of the sides matches the specified size.

When checked, additional space is added to the image to match the specified size.

When checked, only the specified range of frames will be exported.
