How do I set "Automatic Weight" to a single bone?

[Angilas]

Using Weights > Assign Automatic From Bones (as previously suggested) seems to work most of the time, but on occasion it does seem to do things counter to expectation…

Here’s an alternate technique just in case (should work on newer versions too):

1. Create a custom Bone Group for the bones we’re going to use with our desired object.
2. Remove bone deformation for EVERY bone in the armature (for the time being) using Copy to Selected.
3. Select the custom Bone Group for the desired object and then turn on deformation only for said Bone Group (again using Copy to Selected).
4. Now parent the desired object to the armature with automatic weights.
5. Repeat this technique for each desired object you want to parent to the same armature.

Hope this helps any passersby! Peace and God bless!
