使用示例

The article contains the step-by-step implementation of fading-in/fading-out of an object in the scene by means of the Tracker tool:文章包含通过Tracker工具逐步实现场景中物体的淡入/淡出:

  1. Create two objects (e.g box primitives: box1 and box2) with the same transformation and having two materials with different Albedo textures assigned.创建两个对象(例如盒基元:box1box2)具有相同的变换,并具有分配了不同 Albedo 纹理的两种材质。

  2. Make the box1 object transparent by setting Common -> Transparency -> Preset -> Alpha Blend for its material.制作 box1 对象透明通过为其材质设置 Common -> Transparency -> Preset -> Alpha Blend

  3. Open the Tracker tool by choosing Tools -> Tracker in the Menu Bar.通过在菜单栏中选择 Tools -> Tracker 打开 Tracker 工具。
  4. Click to add a new track and choose node -> object -> material -> parameterSlider in the Add Parameter window that opens.单击 添加新曲目并在打开的 Add Parameter 窗口中选择 node -> object -> material -> parameterSlider

  5. 选择透明的box1中的对象Select Node打开的窗口。

  6. 选择box:transparent中的参数Parameter的领域Track Info部分。

  7. Add two key frames for the created track: double-click the track line to add a key frame and set the following values:为创建的轨迹添加两个关键帧:双击轨迹线添加一个关键帧和以下值:

    • For the first key frame, set Time = 0 and Value = 1.对于第一个关键帧,设置 Time = 0 and Value = 1
    • For the second key frame, set Time = 1 and Value = 0.对于第二个关键帧,设置 Time = 1 and Value = 0

注意
If any Z-fighting occurs, you can also adjust Rendering Order for the box1 object’s material.如果发生任何 Z 冲突,您还可以为 box1 对象的材质调整 Rendering Order

The result will be the following:结果如下:
