Maya for 3D Printing - Rapid Prototyping

In this course we're going to look at something a little different, creating technically accurate 3D printed parts.

I am trying to make an eye blink, so what I ahve done is create an incomplete sphere. The tutorial I am working on tells me to open the set driven key thing, select my eye lid then select startSweep and endSweep and it should look like this ......

You need to set up the relationship between the controller and the eyelid so that the driven key feature recognises the link. You can do that through modify/ add attribute.

You then load your driver (the controller) into the set driven key box by selecting it and selecting load driver. You need a driver to key the driven things and as there is nothing in your driver box at present there is nothing to control the blink. Try selecting your controller and loading that as the driver once you have created the relationship. There is a rather good video on set driven keys on 3dbuzz if you wanted to have a look at that; I found it very useful.

Looks like they have both the create nurbs attribute and the object itself linked to the driver in that box.

objects have 2 main nodes, the object node and the shape node. The shape node is the one with the start sweep, etc. One way to select that node is to open the Attribute Editor and click the shape node's tab at the top. Then hit the Select button at the bottom.

after you select it, you have to load Driver or Driven in the Set Driven Key window, depending on which you want that node to be.

I have just clicked that on, did it have to be on when I made my eyeLid. I also deleted the history a while back as a suggestion to another problem.

If you deleted history the createNurbsSphere node will be gone, along with the start and endsweep attributes. The history needs to be on when you create it and it needs to stay for as long as you plan to use the attributes.

Umm, the UI in his screengrab is the channelbox, not the attribute editor. Check out the tutorials in the documentation to brush up a bit on the basics, it will save you a ton of headaches later.
