To change the length of an animation for all skins at once, you can follow these steps:
- Show All Bones/Slots: Press
ctrl+H to ensure all bones and slots are visible. This will help you see all the keyframes in the dopesheet.
- Show All Skin Attachments: In the tree properties, check
Show all skin attachments. This will display timelines for all attachments in all skins.
- Select All Keyframes: Use a box selection to select all the keyframes in the dopesheet.
- Resize the Box: Once all keyframes are selected, you can resize the box to stretch or compress the animation length.
This method ensures that you are adjusting the animation length for all skins simultaneously without having to activate each skin individually.
For more detailed instructions, you can refer to the user guide on scaling keyframes in the dopesheet: Dopesheet - Spine User Guide: Scaling.
