Help with Viewing Set Driven Key details? (working with joint corrective morphs)

[Anonymous]

Hey All,

I'm currently linking blendshapes with skeleton joint rotations/translations - I understand these to be called "joint corrective morphs (JCMs)".

As I understand this, set driven keys is the best way to go about this, but please let me know if there is another (better) viable alternative.

The issue is that after I setup two set driven keys for each morph in the Blend Shape Editor, I can't find a clear place to see the connections. Right clicking in the blendshape editor on the values of a particular blend shape and selecting the first option allows me to see some details in the attribute editor where I can also type in a curve such as "Linear", but it doesn't seem to show me what is actually "linked" such as a shoulder joint rotationX to a particular morph.

I also can't get the graph editor to show the curves mentioned here in autodesk's set driven key guide:

https://knowledge.autodesk.com/support/maya-lt/learn-explore/caas/CloudHelp/cloudhelp/2015/ENU/MayaL...

1) Could anyone let me know if it's possible to see what's connected to what through set driven keys and hopefully along with all the specific value/curve settings?

2) Are there alternative methods to set driven keys? (maybe in the node editor etc?)

3) once I create the set driven keys, the key column red circle, remains red even though of course I'm not actually adding any keys to my animation timeline. Is it possible to turn this red circle off?

All the Best,

Ian

Hi @Anonymous

We do have an article on viewing driven key relationships although I'm not sure if its 100% what you're looking for.

From that article:

After you create driven keys to associate attributes, you can loop through the keys to view the state of the object at each one. This can be helpful as you set more driven keys, or when you’re editing the driven key curve in the Graph Editor.

To examine the state of objects at their driven keys

1. In the scene view, select an object with a driven attribute.
2. From the Set Driven Key window, select Key > Go To Next or Key > Go To Previous.

As for not seeing them in the graph editor, did you select frame all? If so what do you see? Can you possibly post a screenshot of it so I can get a better idea what's happening?

Thanks for the help so far. I'm still experimenting and may have figured it out without knowing what i'm doing differently doh.

It's a slow painful process to test/setup my SDKs because I have a couple hundred blendshapes and as far as I can tell, the SDKs window doesn't allow you to filter so I have to scroll through all my blendshapes doh. Any tips there?

Unfortunately I think that is just a limit of the UI at the moment. That said I know this has been talked about before and mentioned to development so it may be getting changed in the future but I can't say for sure.
