1. Does Hair Shape Key support Blender 4.4?

Yes. The Hair Shape Key add-on is compatible with Blender 4.4. We recommend using v5.8 or newer for best results. If you encounter errors, please provide your Blender version info and add-on version for troubleshooting.

2. Can Hair Shape Key export and import animation data? Can animations be reused across projects?

This feature is not officially released yet. The “Import file as key” button is for developer testing only and is not available for regular users.

3. Can I copy a baked Hair Shape Key and apply it to a different rigging?

Currently, the add-on does not support copying Shape Key.

4. What if hair guides start floating or detach from the scalp after adding shape keys?

Some users reported that guide roots detach after adding shape keys.
Although we haven’t reproduced the issue internally, please help us by providing:
The .blend file where the issue occurs;
A screen recording of your steps (from hair creation to adding shape key).
This will help us isolate and fix the bug.

5. Can Shape Key be applied to multiple hairstyles? Can I use different animations for different timings?

Currently, the add-on supports multiple shape keys on one hair object and can play them. However, it doesn't support copying or sharing shape keys with other objects.

6. Are there conflicts between this add-on and the 3D Hair Brush? Will it affect other modifiers?

The add-on works fine alongside 3D Hair Brush in general. However, older versions may have conflicts, such as:
Activating Hair Shape Key disables some modifiers or controllers in 3D Hair Brush.
This has been resolved in recent updates. Make sure both add-ons are up-to-date.
If you still encounter issues, send error screenshots and version info for support.

7. Why are Shape Keys not animated during playback in Blender 4.1, but work when manually moving the slider?

This is caused by Blender 4.1 not properly calling function update_path_cache() during animation playback.
It’s a known issue in Blender 3.6 and was already fixed. Please update to the latest version of Blender.

8. Can I use Force Field to control hair animation in the add-on?

No. The animation system is based on Shape Key baking and does not support physical force fields. Force fields do not affect the baked animations of Hair Shape Keys.

9. What if I get an error: AttributeError: function 'update_path_cache' not found?

This error occurs in Blender 4.x if the function isn't correctly linked.
It’s already fixed—please update to the latest version of the add-on.

10. Can I give feedback, feature suggestions, or report bugs to you?

Absolutely! We welcome your feedback. You can send us:
Issues encountered (with .blend files, screenshots, or videos);
Suggestions (e.g., batch Shape Key copying, animation management tools);
Contact us via Blender Market comments or our website—we’ll forward your feedback to the development team for review and improvement.
