Stop Tag
Basic TagStop Tag
This tag prevents the object and its children from being affected by generators (Stop Generators enabled) and deformers (Stop Deformer enabled) that are higher up in the hierarchy.
For example, suppose you have a group of objects, one nested inside the other. You place this group inside a Subdivision Surface object. Without a Stop tag, the Subdivision Surface object will affect all objects in the group. If you add a Stop tag to one of the objects in this hierarchy, the effect of the Subdivision Surface will stop at that object and will not affect objects lower down the hierarchy.
The Stop tag affects Subdivision Surface objects, but does not affect deformers. When using the Stop tag with deformers, apply Stop tags to child objects lower down in the hierarchy if they have their own deformers that you want to stop.
