Spline to Position Track

花键定位跟踪

This converts a spline into an animation path. First, select the object whose animation path you want to change. Next, activate the Spline to Position Track command. Based on the first Spline selected in the Object Manager, Cinema 4D will create new X, Y and Z position tracks for the object so that it follows the path of the spline.

这将样条转换为动画路径。首先,选择要更改其动画路径的对象。接下来,激活样条到位置跟踪命令。基于在对象管理器中选择的第一条样条,Cinema 4D 将为对象创建新的 x、 y 和 z 位置轨迹,以便它遵循样条的路径。

Make sure you are not in Link TL/OM Selection mode. Otherwise it will not be possible to select objects and splines separately.

请确保您不处于链接 TL/OM 选择模式。否则,将不可能分别选择对象和样条。

If you are using a B-Spline, you may need to increase the number of intermediate points to ensure a good match between the spline and position track since it can occur that the B-Splines’ control points do not lie on the curve. 如果您使用的是 b 样条曲线,您可能需要增加中间点的数量,以确保样条曲线和位置轨迹之间的良好匹配,因为 b 样条曲线的控制点可能不在曲线上
