Pair Blend

I must admit, I have a new-found love for rigging. The part I enjoy the most is the problem-solving but on the downside being highly technical. This month has been a very intensive month and I’ve learned a lot. I want to go over some of the challenges I had and how I went about resolving some of them. The instructor for the class (Character Rigging I for Full Sail University) has been extremely helpful and is very dedicated in helping students such as myself. On the last project I was working on, he was up til midnight helping me out. Many thanks for that!

I ran into a problem because I haven’t yet understood the selection process in Maya. What I didn’t understand is when selecting under Edit>Select All By Type>Clusters (or whatever type selection you choose) is it not only selects the objects you see on the screen but the  hidden objects as well. What happened to me is I ended up keying hidden objects I didn’t want to key. It caused me to get what is called are pair blend in my translation and rotation attributes. What a pair blend is when two or more things are trying to influence one attribute in the channel box which wasn’t a good thing in my case (in some circumstances, pair blends can be useful rigging tool). You will know if you have a pair blend when your attribute is highlighted green.

To debug this you need to find what is influencing it. The instructor showed me a way to see connections a while back and it has been an extremely useful little bit of information to see what’s influencing it. So the first thing you want to do is select the object you want to investigate and then open your hypergraph window. Then click on the output and input connections icon as seen in the image below.


Then you can see everything connected to that selected object. With your mouse, if you hover over at the lines connecting the nodes together you will see what attributes it’s connecting to (example below). What I ended up doing was breaking the connections of my pair blend attributes and reconnecting my parent constraint I actually wanted influencing my translation and rotation attributes. I hope this as helpful to you as it was to me. 🙂Image

    Omg thank you so much for this! I was dying for a solution to figure out where the devil these things were coming from 😀 My rig is so much cleaner now. I’m sure this knowledge will be useful in the future 🙂

    1. Well I’m glad to be of some help. 🙂
