3ds Max MassFX 教學

3ds Max 內建的 MassFX 是一套物理模擬工具，可使用 Modifier 與 Helpers 製作物理模擬動畫，

MassFX 使用 Rigid body 剛體進行物理模擬，模擬過程中物件將不會改變形狀，剛體可以是以下三種類型：

  • Dynamic: The motion of Dynamic objects is controlled entirely by the simulation. They are subject to gravity, Force space warps, and forces that result from being struck by other objects in the simulation, including cloth objects.
  • 動態對象的運動受到重力，力空間扭曲或其他物體（包括布料物體）撞擊而產生的力的影響。
  • Kinematic: Kinematic objects can be animated using standard methods, but they don't have to be; they can simply be stationary objects. A Kinematic object can affect dynamic objects in the simulation but cannot be affected by them. A Kinematic object can switch over to Dynamic status at any point during the simulation.
  • 可以使用標準方法對運動對象進行動畫處理，但不必如此。它們可以簡單地是靜止的物體。運動學物件可以影響類比中的動態物件，但不能受其影響。運動學物件可以在模擬過程中的任何時間點切換到動態狀態。
  • Static : 靜止不動的物件，與 Dynamic 和 Kinematic 物件不同，可以是 Concave 凹面的，可以當作容器、牆壁、障礙物等。

 

mCloth 修改器也可用於物理模擬，它允許布料物件完全參與類比。

Running the simulation combines the outcome of the physics calculations with your own predefined animations. The result displays entirely within the viewports, in real time or near-real time, depending on scene complexity.

運行模擬會將物理計算結果與您自己的預定義動畫相結合。結果完全顯示在視口中，即時或接近即時，具體取決於場景複雜性。

 

If you are using the plug-in to add simulation to a scene that you will render, you can bake the results to animation keyframes. This speeds up your workflow (fastest repeatable renderings), locks down your results (no unexpected variations), and allows you to tweak the resulting animation as desired. Later, if you need to tweak the simulation, you can unbake the animation, restoring the original dynamic nature of the scene.

 

Additional features of MassFX include:

  • The MassFX Visualizer displays various simulation factors such as object velocities and contact points. This feature is invaluable for debugging simulations.
  • A kinematic body can switch to a dynamic at any point in the animation. During its kinematic phase, it behaves as you animate it and can influence dynamic bodies but not respond to them. For example, you might animate a character swinging a tennis racket up to return a serve. Then, after the body becomes dynamic, it responds to other bodies and forces in the scene. For example, the tennis player might accidentally hit the net, at which point the racket could become dynamic and fly into the air, following the laws of physics.
  • 運動體可以在動畫中的任何點切換到動態。在其運動學階段，它會像您動畫一樣表現，並且可以影響動態物體，但不能對它們做出反應。例如，您可以為揮舞網球拍的角色製作動畫，以返回發球局。然後，在身體變得動態之後，它會對場景中的其他身體和力做出反應。例如，網球運動員可能不小心擊中了球網，此時球拍可能會變得動態並按照物理定律飛向空中。
  • MassFX Explorer is a special version of Scene Explorer dedicated to working with MassFX simulations.
  • MassFX Explorer 是專門用於處理 MassFX 模擬的場景資源管理器的工具。
  • 使用 Constraint 允許物件進行受限制的運動，例如使用門的鉸鏈。
