Houdini 17.0 Nodes VOP nodes

Primitive Attribute VOP node

Evaluates an attribute for a given primitive at the specified uv parametric location.

This operator evaluates an attribute for a given primitive at the specified uv parametric location. The result is stored in adata, which can be one of the following types:

floating-point
integer
vector  (three    floats)
vector4 (four     floats)
matrix3 (nine     floats)
matrix  (sixteen  floats)

In either case, if the attribute data is of a smaller size than adata, an error of 0 will result. A value of 1 is returned upon successful completion.

For example, if attribute Cd is a vector, adata cannot be a matrix or any another structure which can store more than three values.
