So I upgraded unity and my games project. I’ve cleared all of the code based errors it presented.
Every single animation which has a model containing configurable Joints is receiving errors :
Transform position assign invalid…(NaN, NaN, value) where value is the free rotational value of the config joint. Thus if x and y were locked, it generates the errors for them.
transform.position assign attempt for 'LEFT_FOREARM' is not valid. Input position is { NaN, NaN, 22342344711864320.000000 }.
I think it’s related to the animations though, as I do not generate any errors for config joints outside of mecanim animations.
I found this, Unity - Manual: Animation in Unity 5.0, and don’t know A: if it applies to me. B: Where those animation scripts might be or how to access them. C: If I’m barking up the wrong tree thinking it’s the animations rather than the joints themselves.
