Hi Tian,
It’s actually Wayne here…my admin account is temporarily locked out and all the devs are asleep (well it still is the weekend for them anyway)
Could you provide more information?
What doesn’t work?
Does it load, fail to load, throwing an error when you are trying to do a specific thing?
More information is helpful.
The version that is used in the course is bundled with the course downloads. This will 100% work with the version that the course is recorded with.
Newer versions of the add-on also should be backwards compatible up to a point but not totally fool proof.
Other users haven’t had issues – but I’m not always sure what version of Blender they are using.
If you update to 4.2 or above, you can always grab the latest version from the extensions platform.
https://extensions.blender.org/add-ons/bone-widget/
I know we encourage people to use the same version as the course was recorded with.
So my advice would be this.
1. Try to get everything working exactly the same as the course. (same version of Blender + add-on)
If that fails.
2. Update to the latest version of Blender with the extension version of the add-on.
There’s hasn’t been a lot of changes in rigging that affects anything I do in that course.
(I did fix a few bugs though – yes, me…I actually coded the fixes that have been merged into the latest versions of Blender)
If you run into problems just let me know.
