Selecting a bone in weight paint mode in Blender requires a few steps. First, select the armature in the viewport, then select the mesh with Shift + Left Click to make it the active object. Next, enter Weight Paint Mode via the viewport dropdown. Now, you can select a bone on the armature you want to weight paint using Ctrl + Shift + Left Click. It's important to ensure that neither the Paint Mask nor Vertex Selection is highlighted, allowing you to select individual bones. Additionally, the armature should be in Pose Mode, indicated by a blue outline, before starting weight painting.

What You'll Learn
Ensure armature is selected first
When selecting a bone in weight paint mode, it is important to ensure that the armature is selected first. This is a crucial step in the process of weight painting a mesh to an armature in Blender, a software used for 3D modelling and animation.
To ensure the armature is selected first, start by selecting the armature in the viewport or object mode. This can be done by left-clicking on the armature or selecting it by clicking on an object node if it is not already selected. With the armature selected, you can then shift-select the mesh to make it the active object.
It is important to note that the mesh needs to be parented to the armature with armature deform for the bone selection to work in weight paint mode. This can be done by selecting both the mesh and the armature, going to the Parent option, and choosing "Armature Deform" with any of its sub-options.
Once the armature and mesh are properly parented, you can enter Weight Paint Mode. In Blender, this can be done through the viewport dropdown menu or by going to the main Edit menu. With Weight Paint Mode selected, you can now use the Ctrl + Shift + Left Click shortcut to select and edit the bones within the armature.
By ensuring that the armature is selected first, you will be able to successfully select and manipulate individual bones within the weight paint mode, allowing for precise control over deformations and weight distributions.

Shift-select the mesh
To shift-select the mesh, you must first select the armature in the viewport by left-clicking on it. Then, hold Shift and left-click on the mesh to select it. This makes the mesh the active object. It is important to note that the mesh needs to be parented to the armature with armature deform for this to work. This can be done by selecting the mesh, Shift-selecting the armature, and then using the Ctrl + P shortcut to parent them. Once the mesh and armature are parented, you can enter Weight Paint Mode.
In Blender version 4.0 and above, the process of selecting bones in weight paint mode has changed. The new way to select bones is by using the Ctrl + Shift + Left-Click shortcut. This allows you to switch between bone groups being edited. However, simply accessing weight paint interaction mode through the dropdown menu in the 3D viewport will not give you access to bone selection. To enable this functionality, you must first add the mesh to your selection as the active object by holding Shift and selecting the mesh.
In some cases, users have reported issues with selecting bones in weight paint mode, even when using the correct shortcut. One possible solution is to go to Edit > Preferences > Keymap and select Key-Binding mode. Then, type "Ctrl left mouse" in the search field and look for the weight paint section. Delete the "Weight Paint - Ctrl left mouse" line and save the preferences. This should enable bone selection using the Ctrl + Left Mouse Button shortcut.
It is important to note that the Paint Mask and Vertex Selection boxes in the upper left corner should not be highlighted when selecting bones in weight paint mode. If these boxes are highlighted, they need to be deselected so that they are both turned off. This will allow you to select individual bones with Ctrl + Left Click. Additionally, ensure that your mesh is not hidden in Edit mode, as this can also cause issues with bone selection in weight paint mode.

Enter Weight Paint mode
To enter Weight Paint mode, you must first ensure that your "'Active' object has weights." This is denoted by a lighter outline. If you are not seeing Weight Paint mode in the list of interaction modes, this may be because your active object does not have weights.
Once you have ensured that your active object has weights, you can access Weight Paint mode via the top left dropdown menu in Blender's 3D viewport. However, this alone will not give you access to the bone selection method of weight selection.
To add this functionality, you must first hold the Shift key and select the mesh to add the mesh to your selection as the active object. Then, you can access Weight Paint mode.
Now, you can use the Ctrl + Shift + Left Click shortcut to switch between bone groups while editing.

Check Paint Mask and Vertex Selection are off
When selecting a bone in Blender's Weight Paint mode, it is important to ensure that the Paint Mask and Vertex Selection are not highlighted. These settings can usually be found in the upper left corner of the interface.
By ensuring that these options are not selected, you can avoid potential issues and gain the ability to select individual bones using the Ctrl + Left Click shortcut. This is a crucial step when setting up weights for your project.
In Blender version 4.0 and above, the process of selecting bones in Weight Paint mode has evolved. To select a bone, you now need to use the Ctrl + Shift + Left Click shortcut. Before attempting this shortcut, make sure that the Paint Mask and Vertex Selection are indeed deselected.
Additionally, it is important to note that your active object should have weights. If you are not seeing Weight Paint mode in the list of interaction modes, it may be because your active object does not have weights. Ensure that your active object, indicated by a lighter outline, is the object with weights.
By following these steps and ensuring that Paint Mask and Vertex Selection are off, you will be able to successfully select bones in Blender's Weight Paint mode.

Ctrl + left-click to select bone
To select a bone in weight paint mode, you need to first set up your armature and mesh. Start by selecting your armature in the viewport with a left click. Next, select your mesh with Shift + Left Click. This makes the mesh the active object. Now, go into Weight Paint Mode via the viewport dropdown.
Now, to select a bone, you can use the Ctrl + Shift + Left Click shortcut. This will allow you to select the bone you want to weight paint. It is important to note that you need to make sure that neither the Paint Mask nor the Vertex Selection is highlighted in the upper left corner. They should both be turned off so that you can select individual bones.
If you are using an older version of Blender (before version 4.0), the shortcut might be different. In Blender 3.6, for example, the shortcut was Ctrl + Left Click. However, with the newer versions, the hotkey has changed to Ctrl + Shift + Left Click.
Additionally, if you are having trouble selecting bones in weight paint mode, make sure that your mesh is parented to the armature with armature deform. This is a necessary step to be able to select the bones. Also, ensure that your active object has weights assigned to it, as weight paint mode may not appear otherwise.
