How can I change the color of a 3d object in animation?

Question

Unity

Such a problem. There is a 3d model of the character. I want it to glow red when it takes damage. I wanted to make an animation, but the object does not have the usual 2d Color field.

How to do it?

Answer 1

The material must have a _Color field.
You will create a script that will change the color value through "material.SetColor ()" (if I'm not mistaken).

public class MyCode 
{
  [SerializedField] private Color _color = Color.red;

  // Соединяешь материал что используется в MeshRenderer (из ресурсы).
  [SerializedField] private Material _mat; 

  public void TakeDamage()
  {
    // ...
    // блаблабла
    // ...

    StartCoroutine(ChangeColor());
  }

  private IEnumerator ChangeColor()
  {
    float speed = 5;

    // Изменение с белого на красный
    for(float t = 0; t < 1; t += Time.deltaTime * speed)
    {
      _mat.SetColor("_Color",  Color.Lerp(Color.white, _color, t));
      yield return null;
    }

    // И обратно.
    for(float t = 0; t < 1; t += Time.deltaTime * speed)
    {
      _mat.SetColor("_Color",  Color.Lerp(_color, Color.white, t));
      yield return null;
    }
  }
}
