maya船在水面的运动轨迹

maya船在水面的运动轨迹
maya中怎么做船在水面行驶出的痕迹阿?
就是船开过水面的纹理

用Maya Ocean
再问： 用的海洋材质？ 可是运动的时候会有轨迹嘛？
再答： User Guide > Dynamics and Effects > Fluid Effects > Open water effects > Make boats float 看文档中的这个章节。 1.Select Fluid Effects > Ocean > Create Ocean > . The Create Ocean options window appears. 2.Turn on Attach to Camera and Create Preview Plane, and then click Create Ocean. 3.Select the boat geometry. 4.Select Fluid Effects > Ocean > Make Motor Boats. Maya attaches a locator to the boat with built-in expressions to simulate buoyancy effects. 5.Select the perspective camera (persp) and select Edit > Group. This creates a group and puts the perspective camera in it. 6.In the Connection Editor(Windows > General Editors > Connection Editor), do the following: •Connect the boat locator (created in step #4) Translate x and Translate z attributes to the transform (ocean height field) Translate x and Translate z attributes respectively. •Connect the locator Translate x and Translate z attributes to the camera group (created in step #5) Translate x and Translate z attributes. This connects the movement of the boat along the ocean plane to the ocean and to the movement of the camera. 7.Select the boat locator and in the Attribute Editor open the Extra Attributes section. 8.Switch to shaded mode. 9.Playback the scene and adjust the throttle and rudder settings.
