If I connect modular meshes to the Base Skeletal Mesh using Master Pose Component, will their morph targets play automatically with animations, or do I need to drive them manually?

For example, let’s say my base skeletal mesh (the body) has a bicep flex animation. The base mesh also has a morph target that bulges the bicep during that animation.

Now, I also have a modular shirt mesh that has its own morph target called “SleeveStretch” to make the sleeve expand when the arm flexes.

If I connect the shirt to the base skeletal mesh using Master Pose Component, will the shirt’s “SleeveStretch” morph automatically trigger when the body’s bicep flex animation plays? Or do I need to manually drive the morph on the shirt?

In Blender, the “SleeveStretch” morph is animated along with the bicep flex animation.
