Question OnValidate() not working with animation

Hey Devs,
I have a script to control multiple blend shapes of skin mesh renderers. The script has floats and an OnValidate() void. Whenever the float changes, the blend shape weight should change. This works normally in real-time, however, when an animator controls the floats of that script, the blend shape weights are no longer changing.

Code (CSharp):

1. public float B1Value;
2. public SkinnedMeshRenderer smr;
3.  
4. void OnValidate()
5. {
6.      smr.SetBlendShapeWeight(1, B1Value);
7. }

What should I do to make OnValidate() work in animations and change blend shapes?

 

Anyone from Unity Technologies?

 

Unfortunately it's not possible to use OnValidate on runtime because it is editor only function. You can define a float in the animator and access it by using "animator.GetFloat()" in the Update. That way whenever you change the variable in the animator by some animation, it will be updated directly.
