Modifiers

Modifiers are a type of node that applies its effect to a number of other nodes in the entire graph structure. Modifiers can merge Mesh Sections, clip geometry, etc. The way to decide what other nodes are affected, is by using Tags. They type of node that can be affected by a Modifier dependes on the type of modifier, but it is basically Mesh Section Nodes.

All modifiers have a common set of properties:

• Required Tags : Is a list of tags that other nodes must have so that the effect of this modifier is applied to them. If a modifier has no tags, it will not affect anything.
• Multiple Tag Policy: Decides what to do when more than one tag appears in the above list.
  • Only One Required : As long as the other node has any of the tags in Required Tags, the modifier will be applied to it.
  • All Required : The other node must have all the tags listed in this modifier in order to get its effect applied. It can have additional unrelated tags though.
