AnimatorCullingMode

Режим отбора для Animator.

Чтобы указать, как Animator управляет анимациями объектов, которые могут быть не видны, задайте значение из этого перечисления в Animator.cullingMode.

using UnityEngine;

// This example demonstrates how to change the culling mode of an Animator component based on the distance between the
// object and the main camera. This can be useful to optimize performance by disabling animations when objects are far
// away from the camera.
[RequireComponent(typeof(Animator))]
public class AnimatorCullingModeExample : MonoBehaviour
{
    // The distance at which the Animator culling mode is set to CullCompletely.
    public float distanceToEnableCulling = 100.0f;

    Animator m_Animator;

    void Start()
    {
        m_Animator = GetComponent<Animator>();
        m_Animator.cullingMode = AnimatorCullingMode.AlwaysAnimate;

            Debug.LogError("There is no main camera in the scene.");
