After animating a custom material/shader parameter, how do I get an accurate value from script?
For example, I create a new shader with a Color parameter, then create a new material that uses that shader.
I assign that material to a new 3D object, and use an Animator (on another object) to animate that object's material's Color values. Hitting Play, I can see the object changing color correctly.
However, I have a component on the object where I just want to query the current animated color from the material. e.g.
void Update {
Debug.Log(GetComponent().material.GetColor("_Colour"));
Debug.Log(renderer.material.color);
Debug.Log(GetComponent().sharedMaterial.GetColor("_Colour"));
Debug.Log(renderer.sharedMaterial.color);
}
All of these only output the value that the Color attribute was BEFORE playing, not while the animation is live. How can I get the live animated value?
Same problem here. I can't find a way to get the actual color of that material, which gets correctly displayed by the editor.
Just found an answer! I noticed a message in the inspector saying that a MaterialPropertyBlock is used to control the values. I guess the animator does that during playmode.
Reading from the property block solves this issue:
MaterialPropertyBlock properties = new MaterialPropertyBlock();
renderer.GetPropertyBlock(properties);
Vector4 color = properties.GetVector("_Color");
Debug.Log("color: " + color);
Try use the LateUpdate event, it works the same way but gets called after the animations.

Been wracking my brain trying to figure this out and scouring forums for this. Was trying to get the animation > animation.clip > animation.clip.property(curves, component, etc) so Thank You!
