Unity 过度光照贴图

背景：开关窗帘过程，让环境在亮和暗之间过度

 

事先烘培出亮、暗两张Lighting map。然后代码实现，窗帘开关由动作实现，而代码中通过动作执行进度来过度两张Lighting map

void OnAnimatorMove()
{
    AnimatorTransitionInfo transitionInfo = animator.GetAnimatorTransitionInfo(0);
    if (transitionInfo.normalizedTime != 0)//状态切换中
    {
    }
    else
    {
        AnimatorStateInfo currentAnimatorStateInfo = animator.GetCurrentAnimatorStateInfo(0);

        // 开窗
        if (currentAnimatorStateInfo.IsName("opening"))
        {
            LightmapBlender.Instance.OpenWindow(currentAnimatorStateInfo.normalizedTime);
        }

        // 关窗
        if (currentAnimatorStateInfo.IsName("closing"))
        {
            LightmapBlender.Instance.CloseWindow(currentAnimatorStateInfo.normalizedTime);
        }
    }
