This Houdini 9 software video series focuses on examples of when and how to use Attribute Transfer.
Part 1 covers Attribute Transfer One Point:
A very basic example of how to use the attribute transfer sop, by using a single point to transfer a colour attribute to a grid.
Part 2 covers Attribute Transfer Line SOP:
Continuing from the first lesson, using a line sop and transfering rand point colours to the grid.
Part 3 covers Attribute Transfer Point Switches:
A further addition to the previous two lessons with the introduction of a point sop to generate random colours and switch sops to manage the display of multiple inputs.
Part 4 covers COP Ramp "tex" Function:
Expanding on the flexibility of the point sop by introducing the "tex" function to read the colour values of an image and distributing colour values to points. A ramp is used in a composite editor. As well, there is a brief discussion of the importance of node ordering.
Part 5 covers: Attribute Promote Mountain Normals:
An introduction to the attribute promote sop and illustrating how transferring normal attributes from another object can influence how to control the lighting of a surface.
By the end of this Houdini 9 tutorial you should be comfortable transfering attributes from within any part of Houdini 9 be it modeling, animating or working with particles or other effects components.
