Mesh Onion Skins is a Blender add-on that helps to create and analyze object or character animation. Onion skinning, in computer graphics, is a technique used in creating animations to see several frames at once. This way, the animator can make decisions on how to create or change a frame based on the previous frame in the sequence.
How does it work? Mesh Onion Skins add-on has 'GPU' and 'Mesh' draw modes, that you can choose from.
'GPU' mode is designed to be fast in term of viewport performance and less in time creation, but it is not present as a mesh data, therefore less possibilities in their data manipulation.
'Mesh' mode, basically, makes duplicate objects of the corresponded frame and applies to them several properties at the specified frame range. All duplicated objects (onion skins) are stored in the newly created collection and can be found in the Outliner. Stored collected data can be rendered with EEVEE or Cycles, or can be served for other purposes.
Supported Blender version: 2.83+, 3.0+
- Open Blender and select Edit->Preferences
- Click Add-ons category and then 'Install...' button
- Select the downloaded archive file
- Check the 'Mesh Onion Skins' option in the add-on dialog
Mesh Onion Skins 1.1.2
- New feature Settings Presets, helps you to quickly save and load predefined properties that suits best to a particular phase in the creation or analysis of the animation.
- New feature Auto Update Skins, that updates onion skins on changing keyframe or animation. It triggers after insert, delete or change keyframe, switching active bone if the corresponding keyframe filter is enabled, basically if there is any difference in the current action of the object. Also, to reduce updating time, this feature has some properties, that allows you to fine tune the amount of frames to be updated.
- Some small fixes.
Mesh Onion Skins 1.1.0
- Prepare the use of the GPU module in Blender 3.0.0 in case of bgl module become obsolete.
- Use active object instead of selection while updating motion path.
- Fix various handlers not being removed on unregister.
Mesh Onion Skins 1.0.9
This update dedicated to 'Mesh' draw mode exclusively. Even if this mode is a slower approach, but a more convenient solution in some cases.
- Improve mesh creation, make it more reliable and much faster (real fast if 'Display Progress' turned off)
- Added the keyframes view range frames type for 'Keyframes' draw method, similar as it is in GPU mode.
- Added support for overridden libraries and proxies. (A small tip for proxy rigs, just make sure that rig hierarchy tree in library file does not contain animation data. It might break some rig functionality, but will help you to solve some issues if you find any.)
Mesh Onion Skins 1.0.8
- Added support of Sculpt mode, that can be used with the Keymesh add-on. Only Solid Viewport Shading is working with the GPU draw in that mode. Please, use the latest version of Keymesh add-on located on the page of the developer https://github.com/pablodp606/keymesh-addon
(Blender 2.92+ is strongly recommended)
Mesh Onion Skins 1.0.7
- GPU Mode:
- Added support to linked proxy rigs.
- Now is possible to operate with multiple armature rigs in Pose mode.
- Added new Preference settings that helps you to change several properties that will be loaded by default in startup file, or in files that does not contain scene settings for the add-on.
- New operators to save and load Preference settings.
- New operator 'Show Preference Settings' that opens the Preferences Editor with the add-on settings.
- Code cleanups, optimizations and various fixes (update is recommended)
Mesh Onion Skins 1.0.6
- Fix depsgraph update issue
- Fix weren't drawing skins of objects in overridden libraries if View Range being turned off ('GPU' mode only)
Mesh Onion Skins 1.0.5
- Added New 'GPU' Draw mode that much faster than previous one. Credit goes to iBrushC, due to his work development turned in the right direction. Thanks to his findings based on this https://docs.blender.org/api/current/gpu.html documentation. You can find more of iBrushC work at his github page https://github.com/iBrushC/animextras. Old 'Mesh' mode preserved, mostly, to render onion skins in EEVEE or Cycles, for instance, or for other purposes.
- In the draw frame method 'In Range' added new option 'Action Range', that includes all frames of the current animation range in the onion skin creation process.
- In the draw frame method 'Keyframes' added new option 'All Keyframes', that includes all keysframes of the current animation in the onion skin creation process.
- Added new 'Keyframes' option in the View Range section, that helps you to preview onion skins in a range of frames that contains selected number of keyframes.
- Various small fixes.
Mesh Onion Skins 1.0.1
- Fix the exception for objects with NoneType material slot if Colors has been turned off
You'll get: 1) Mesh Onion Skins add-on for Blender in the archive file ready to be installed. 2) Blender file with an animated mannequin sample that you can see in the cover image.
