Import Vertex Attribute can fetch the attribute value from a geometry stored on disk.
The Geometry Global
vtxnum is a linear vertex number. Thus you should
not wire both
What type of attribute data to fetch. The attribute should be large enough to fill out the desired size. For example, a vector attribute needs to be a float attribute of size 3. Therefore to fetch color, you'd use Vector Attribute.
If the attribute cannot be imported because it does not exist, or is not a compatible type, or the specified element is invalid, this will be the resulting value.
You can fetch attributes from one of the inputs to the current operator rather than a file. When set to other than File, the Geometry File is overridden. This allows you to refer to a SOP operator without the op: or opinput: syntax.
The file on disk to fetch an attribute from.
The name of the attribute to fetch.
Cd fetches the common color attribute, and
P will fetch point position.
The primitive to fetch from. If not specified, the vertex number is taken to be a linear vertex.
The vertex to fetch from. If a primitive is specified, this is the vertex within that primitive. Otherwise it is a global linear vertex number.
If it isn’t specified, the current vertex (which is a linear vertex number!) is used.
