That is why the focus of this tutorial is related to the RIB archive. Since the RIB archive is a geometry property it needs an host that will support it. Most of the case it should be a simple representation of the real object. In this tutorial we will first show you how to create an host that will cover the bounding box of the original object. To be more pipeline oriented, we will use a simple Python script in order to generate the bounding box of a selected object:
...
At this point, you have just exported your first object as a RIB file and use it for rendering.
You will see that when rendering the result will display the “real” object with the exact same look. Also with this solution, you will still be able to apply transforms to the RIB object and also you will be able to edit the shader, override it or even use camera projection on it.
This can be a major advantage when you are working on very complex scenes.
