I’m Ayana, a Vtuber!
Today I will explain about Armature association.
With automatic weights
First of all, I will explain how to associate with automatic weights.
In Object mode, select the robot, choose armature, press Ctrl + P, then click [With Automatic weight] to link the robot with its Armature.
When [Automatic weight] has been linked, I will try to make robot move.
After switching to pose mode from the switch menu in the top left of the 3D viewport, select the bone you want to move and try rotating or moving it. If you look closely, you can see that when you move the top left arm, the shoulder part is hung up and moves unnaturally. In this case, you need to edit the weights.
Press A to select all the bones and press Alt + R. Then you can return the model to its original pose.
Manual association method
Next, I will guide you the manual linking method. I will let the robot hold a stick and connect with hand movement.
Firstly, prepare such a rod-shaped object and move it to the position of the left hand.
Select the stick, open tab [Modifier properties], then click [Add Modifier] and choose Armature.
Select [Armature] from [Object:].
Next, select Armature, open tab [Object data properties] and tick on [Names].
Then, the name of the bone will be displayed like this. At this time, we can see that the bone named [Hand.L] is associated with the stick object.
Select the stick object again and click [Object Data Properties]. From [Vertex Group], click + on the top right to add a new vertex group. At this time, change the name to “Hand.L” , the same name with the bone that links the movement.
Press the Tab key to switch to edit mode, and after selecting all the stick meshes, set the weight to 1.000 from the [vertex group] and click [Assign].
If you switch to pose mode and move the left hand, you can see that the left hand and the stick are moving like this.
This is the end of the lecture on how to associate Armature.
How is everyone doing?
