Invalid Driven Object

Janooba 4 months ago updated 4 months ago 2

I'm trying to create a custom property that can be used to curl all fingers in a hierarchy, but I'm getting this error upon assigning Rotation X to it. I don't know what this means, or how I can solve the issue.

Hi,
thank you very much for your support request.

You need to change the rotation interpolation mode of your finger joints to "Euler Rotation".


By default, all joints use quaternions to represent the rotation (this is a 4 dimensional representation of an orientation, hard to imagine and thus makes no sense to manipulate one coordinate of it directly via a custom property constraint).

Here is a detailed video tutorial covering this topic:

Please let me know in case you have any follow-up questions.


Best regards,
Peter
