The normal attribute node can also be used for scenarios like separating the geometry, deleting our geometry, or even extruding it.Īll we need to do is know how to call that specific attribute to be used when a node requires it. An example of this would be to use the position attribute to call the separate geometry node to select specific vertices to take apart from the main mesh. In Blender, attributes are primarily used to control our node systems by defining what some of our parameters are calling. Some of these attributes will be pre-built such as the normal attributes for faces and the position attributes for points or vertices. The element in which an attribute is stored can also be referred to as a domain and an example of a domain can include edge, face, or vertex data.ĭifferent domains will have different attributes associated with them. This data can take on a variety of different forms or types, such as vector data or Boolean data. In order to successfully use our normal attribute, we first need to be able to identify where the normal attribute is located in Blender, what type of data it is, and the various ways in which it can be used for our geometry node system.īefore we can focus on the normal attribute itself, we need to answer the question of what an attribute is in geometry nodes.Īn attribute refers to a specific type of data that is stored per element. The normal attribute can also be used in other scenarios as well to control the selection and direction of our influenced geometry.
The normal attribute defines the direction of our face domain, allowing us to control other nodes such as the extrude mesh node to determine which of our faces are going to be extruded.
When working with geometry nodes, we also have the ability to work with the various attributes associated with our geometry that can be used to influence our node setups. How To Use The Normal Attribute For Geometry Nodes
