Key Properties

关键属性

Note that most of the settings described here can also be defined in the Project Settings menu’s Key Interpolation as a default for newly created keyframes.

请注意，这里描述的大多数设置也可以在项目设置菜单的键插值中定义为新创建的关键帧的默认设置。

Key Time

关键时刻

This key is located on the current time in the animation.

此键位于动画中的当前时间。

Lock Time

锁定时间

Use this setting to lock a key at a specific location so it cannot be moved horizontally, neither in Dope Sheet mode nor in F-Curve mode.

使用这个设置将钥匙锁定在一个特定的位置，这样钥匙就不能水平移动，既不能在涂料表模式下也不能在 f 曲线模式下。

Locked keys (with regard to time) are given a different color in the Key and F-Curve modes so they can easily be differentiated.

锁定键(关于时间)在键和 f 曲线模式给出了不同的颜色，所以他们可以很容易地区分。

Key Value[-∞..+∞]

键值[-∞ . . + ∞]

This is the scale value saved within the key. This can represent a position, the brightness of a light, an option’s activated or deactivated state or one of a thousand other properties that can be animated.

这是键中保存的缩放比例值。这可以表示一个位置，一个光的亮度，一个选项的激活或停用状态，或一千个其他属性可以动画。

Lock Value

锁值

Use this setting to lock a key’s value to prevent it from inadvertently being changed.

使用此设置锁定键的值，以防止无意中更改该键。

Locked keys (with regard to key value) are given a different color in Dope Sheet mode.

在涂料表模式下，锁定的钥匙(关于键值)被赋予不同的颜色。

Interpolation

插值

Use this menu to define how the interpolation between the active key and the next key should be calculated. The following options are available:

使用此菜单定义应如何计算活动键和下一个键之间的插值。以下方案可供选择:

• Spline: This is the most common type when creating realistic animations in which objects accelerate and decelerate. 样条: 这是最常见的类型，当创建现实主义动画中的对象加速和减速
• Linear: The change in value will remain constant. 线性: 值的变化将保持不变
• Step: No interpolation will take place. A key value will remain unchanged until the next key is reached, at which point the value will jump to the next value. This option is good for on / off animations in which the jump to another value is intentional. 步骤: 不进行插值。键值将保持不变，直到到达下一个键，此时该值将跳转到下一个值。此选项适用于有意跳转到另一个值的开/关动画

Quaternion Interpolation

四元数插值

Details regarding the Quaternion functionality can be found under Quaternion Rotation.

关于四元数功能的详细信息可以在四元数旋转下找到。

You can use the options in this menu to temporally affect the Quaternion interpolation (the rotational values saved in the keyframes will remain unchanged) Linear (SLERP) animates temporally in a linear fashion (i.e., with identical velocity) while Cubic near a keyframe will decelerate (approximately comparable with an FCurve’s horizontal tangent).

您可以使用此菜单中的选项临时影响四元数插值(关键帧中保存的旋转值将保持不变) Linear (SLERP)以线性方式(即，具有相同的速度)临时动画，而 Cubic 在关键帧附近将减速(与 FCurve 的水平切线大致相当)。

Linear (SLERP) represents the "linear" and Cubic the "losh" setting for the Quternion tag.

Linear (SLERP)表示 Quternion 标签的“ Linear”和“ Cubic”设置。

Mute

哑巴

If a key is muted, the key will be treated as if it does not exist and the F-Curve will no longer run through it. However, the key can still be selected and reactivated. A change in value from an alternate source, such as an Expression (Vibrate tag) for example, can be implemented within this range.

如果一个密钥被静音，则该密钥将被视为不存在，并且 F-Curve 将不再运行。但是，密钥仍然可以被选择和重新激活。可以在此范围内实现来自备用源的值更改，例如表达式(振动标记)。

Breakdown

分解

Breakdown keys are special keys that, for example, depict a special character pose or another important animation state. These allow for the fine tuning of very tight animation sequences. If the key values should remain the same when moved, simultaneously press the Shift key.

分解键是特殊的键，例如，描绘一个特殊的角色姿态或其他重要的动画状态。这些允许对非常紧凑的动画序列进行微调。如果移动时键值应保持不变，则同时按下 Shift 键。

Breakdown keys are otherwise the same as normal keys and possess the same properties, which can also be edited in the Attributes Manager.

分解键与普通键相同，具有相同的属性，也可以在属性管理器中进行编辑。

Breakdown Color

分解颜色

This option can be used to assign a different (single!) color to keyframes, e.g., to mark important keys or poses. This color will be displayed at all corresponding locations (e.g., Timeline, Animation Palette, etc.). No other key properties will be affected.

此选项可用于分配不同的(单!)给关键帧添加颜色，例如，标记重要的键或姿势。此颜色将显示在所有相应的位置(例如，时间轴，动画调色板等)。不会影响其他关键属性。

Several new settings were added to the Timeline to make working with F-Curves even easier by helping you create better and softer F-Curves. Constantly adjusting tangents after moving keys used to be unavoidable. This has now, in part, been automated and made stepless. The main goal of the improved handling is to ensure the creation of soft, flowing transitions between keys and avoiding overshoots.

一些新的设置添加到时间线，使工作与 f 曲线更容易，帮助您创建更好和更柔和的 f 曲线。在移动按键后不断调整切线是不可避免的。这在一定程度上已经被自动化并且无级化了。改进的处理的主要目标是确保在键之间创建柔和、流畅的过渡，并避免超调。

Key Preset

预置键

Key presets are each a combination of keyframe properties (click on the small arrow on the left next to Key Preset to display these) that work well together. You can select from the following:

按键预置是每个组合的关键帧属性(点击左边的小箭头旁边的关键预置显示这些) ，以及一起工作。你可以从以下选择:

• Custom 习俗: This option will be shown if you use a unique combination. : 如果使用独特的组合，则会显示此选项
• AutoKey Classic 自动键经典: The Auto Tangents will behave exactly like they did in pre-R17 Cinema 4D versions. : 自动切线将表现完全一样，他们在前 r17C4D 版本
• AutoKey No Overshoot 自动键无超调: Like : 喜欢AutoKey Classic 自动键经典 but with optimized, stepless overshoot prevention. 但是有了最优化的，无级超调预防
• AutoKey Weighted 自动键加权: Use this mode if you are not sure which one to use. This mode applies most of the new options. : 如果不确定使用哪一种模式，请使用此模式。这种模式适用于大多数新选项

Unfortunately these presets can’t be applied strictly to a single animation task (e.g., character animation or technical animations). There are only different types of behaviors for Auto Tangents. You can test which presets you want to use or if you would rather use a unique combination, depending on your individual workflow.

不幸的是，这些预设不能严格应用于单个动画任务(例如，角色动画或技术动画)。自动切线只有不同类型的行为。您可以根据自己的工作流程测试希望使用哪个预置，或者是否希望使用唯一的组合。

Auto Tangents

自动切线

This tangent mode has predefined values and should only be applied in conjunction with the Spline interpolation type. Auto Tangents automatically sets tangent length and angle to a soft interpolation. The tangents will run horizontally from the first key to the last key.

这个切线模式有预定义的值，应该只与样条插值类型一起使用。自动切线自动设置切线的长度和角度，以软插值。切线将从第一个键水平运行到最后一个键。

Slope

斜坡

You can choose between two methods for automatically creating tangents:

你可以选择两种方法来自动创建切线:

• Classic 经典: This is the method used in pre-R17 versions of Cinema 4D. When a keyframe (or a neighboring key) is moved, the tangent slope is variable and it changes the closer you are temporally to a neighboring key. In general, softer curves will be generated. : 这是在前 r17版本的 Cinema 4D 中使用的方法。当一个关键帧(或者邻近的密钥)被移动时，切线斜率是可变的，并且它会随着你临时靠近邻近的密钥而改变。一般来说，会产生较为柔和的曲线
• Fixed Slope 固定斜坡: The tangent slope remains constant between two neighboring keys (as long as these aren’t modified or affected by options such as : 两个相邻键之间的切线斜率保持不变(只要这些键没有被修改或受到下列选项的影响Clamp 夹钳). The key can be moved while maintaining a constant tangent slope. This mode works best in conjunction with the ).键可以移动，同时保持一个恒定的切线斜率。这种模式最好与Weighted Tangent 加权正切线 option. 选择

Clamp

夹钳

This special setting lets you prevent overshoot in soft interpolations Auto Tangents between keys with the same value. Normally overshoot is not critical, although it can be bothersome at times. For example, if an animated foot should not sink into the floor when it steps.

这个特殊的设置可以防止在软插值键之间的自动切线与相同的值超出。正常情况下，超调并不严重，尽管有时会令人烦恼。例如，如果一个动画脚不应该陷入地板时，它的步骤。

Clamp replaces the soft interpolation between 2 keys (this setting must be activated for both keys) with the same value with a linear interpolation. If the value of one of these keys should later be changed, Clamp will no longer apply and the normal interpolation will take place.

箝位替换2个键之间的软插值(这个设置必须为两个键激活)与相同的值与一个线性插值。如果其中一个键的值以后应该更改，箝位将不再应用，并且将进行正常插值。

In addition, local Maxima and Minima (keys whose neighboring keys to the left and right are larger or smaller), as well as a track’s first and last keys will be assigned horizontal tangents

此外，本地极值(左右键的相邻键大小不一)以及音轨的第一个和最后一个键将被分配水平切线

Remove Overshooting

消除过度调整

This option is very similar to the Clamp option with the difference that the ,overshoot prevention’ does not set in abruptly when the key value deviates from that of the neighboring key (whereby a brief overshoot can nevertheless occur) but the tangents will be more horizontal the closer they are to the limit. This means that no overshoot will take place.

这个选项与箝位选项非常相似，但是不同的是，当键值偏离相邻键值时，超调预防不会突然设置(这时可能会出现短暂的超调) ，但是切线越接近极限越水平。这意味着不会发生超调。

Note how the tangents in the image above are more horizontal the closer the key values comes to the neighboring key’s value.

请注意，上图中的切线越靠近邻键的值，其水平程度就越高。

Weighted Tangent

加权正切线

If this option is disabled, weighted tangents will change their tangent length according to the distance from the neighboring key if the Auto Tangents option is also enabled. The closer the neighboring key lies, the shorter the respective tangent half will be (the opposing half will be lengthened accordingly). Depending on the Slope option selected, this will be done differently but this is something that isn’t relevant at this point. The slope will remain the same whether or not this option is enabled or disabled.

如果这个选项被禁用，加权切线将改变他们的切线长度根据距离相邻的关键，如果自动切线选项也被启用。相邻的键越靠近，相应的切半就会越短(相对的切半会相应地加长)。根据选择的 Slope 选项，这将以不同的方式完成，但这是与此无关的事情。无论启用或禁用此选项，斜率都将保持不变。

The ratio of short and long tangents can only be defined freely by breaking the tangent manually.

短切线与长切线的比值只能通过手工切断来自由确定。

A tangent whose halves are different lengths automatically produce somewhat more uniform F-Curve shapes.

不同长度的切线会自动产生更均匀的 f 曲线形状。

If the Auto Tangents option is disabled, the ratio between left and right tangents will remain constant when keys are moved. If you drag an unbroken tangent, the length of the other tangents will change relative to the length of the previous tangent.

如果禁用“自动切线”选项，则当键移动时，左右切线之间的比率将保持不变。如果拖动一个不间断的切线，其他切线的长度将相对于前一个切线的长度发生变化。

If this option is disabled, the unbroken tangent halves will be reset to equal lengths.

如果此选项被禁用，不间断的切线一半将被重置为等长。

Automatic Weighting

自动称重

If this option is enabled, a one-time weighting as described for the Weighted Tangent option will be applied. After that, the tangent’s Time(=X) component will be fixed. The tangent handles can then only be moved vertically and the tangent itself can only be rotated. When the key is moved, the slope will remain constant. This option behaves similarly to the auto tangent functions in other applications.

如果启用此选项，将应用加权切线选项描述的一次性加权。在此之后，切线的时间(= x)分量将被固定。切线手柄只能垂直移动，而切线本身只能旋转。当键移动时，斜率将保持不变。此选项的行为类似于其他应用程序中的自动正切函数。

Left Time
Right Time
Left Value[-∞..+∞]
Right Value[-∞..+∞]

左时右时间左值[-∞ . . + ∞]右值[-∞ . . + ∞]

This is where the tangent handle coordinates, from the key outward, are displayed. In most cases it will not be necessary to manually make any changes. It is much easier to edit the tangents interactively in the F-Curve mode. As a reminder: The following keys can be used when editing tangents (Shift also works in conjunction with Ctrl/Cmd and Alt):

这就是从键向外显示切线句柄坐标的地方。在大多数情况下，不需要手动进行任何更改。在 f 曲线模式下，交互式编辑切线要容易得多。提醒一下: 在编辑切线时可以使用以下键(Shift 也可以与 Ctrl/Cmd 和 Alt 一起使用) :

• Shift 转移 : Tangents will be broken; left and right tangents can be edited separately. 切线将被打破; 左右切线可以分别编辑
• Ctrl/Cmd : Only the tangent length can be edited. : 只能编辑切线长度
• Alt 谷丙转氨酶 : Only the tangent’s angle can be edited. : 只能编辑切线的角度
The effects of using these keys can be limited by opposing settings (e.g., applying the 使用这些键的效果可以通过相反的设置(例如，应用Ctrl 1. Ctrl-key will not override the Lock Tangent Length option). - key 不会覆盖 Lock Tangent Length 选项)

Lock Tangent Angles

锁定切线角度

Use this setting to lock a tangent’s ascension. The animation velocity in the vicinity of the key will remain constant.

使用此设置来锁定切线的上升。键附近的动画速度将保持不变。

A tangent’s handles will be marked with a colored edge and only its length can be edited. The Ctrl-key can be pressed while editing a tangent’s handles in order to maintain a constant angle.

切线的句柄将用彩色边标记，并且只有其长度可以编辑。可以在编辑正切操作柄时按下 ctrl 键，以保持一个恒定的角度。

If the Lock Tangent Lengths is also enabled the key tangents will be hidden.

如果锁定切线长度也是启用的关键切线将被隐藏。

Keep Visual Angle

保持视角

With this option you can keep the angle between left and right tangents constant. This option is only available for broken tangents (angle between both not equal to 180°).

使用这个选项，您可以保持左右切线之间的角度不变。此选项仅适用于断开的切线(两者之间的夹角不等于180 °)。

Lock Tangent Lengths

锁定切线长度

Activate this setting to lock a tangent’s length. Only the tangent’s rotation can be changed. The ALT-key can be pressed while pulling a tangent’s handles in order to temporarily maintain a constant length.

激活这个设置来锁定切线的长度。只有切线的旋转才能改变。该 ALT-key 可以按下，同时拉一个切线的手柄，以暂时保持一个恒定的长度。

If the Lock Tangent Angles is also enabled the key tangents will be hidden.

如果锁定切线角度也是启用的关键切线将被隐藏。

Break Tangents

打破切线

Activating this setting will let you edit the left and right tangents independently of one another. The tangent’s handles will change from a triangular shape to a disc shape.

激活这个设置可以让你独立编辑左右切线。切线的手柄将从三角形变成圆盘形。

Using broken tangents will result in a jerky motion.

使用断开的切线会导致跳动。
