There are two different types of animation blending in Track View: Cross-Fade blending and Gap-Blending.

Cross-Fade blending

This blending method automatically kicks in if two animations overlap each other. The blending affects the whole section where the animations intersect – the "weight" of the second animation will steadily increase towards the intersection's end. At the start of the 2nd animation the weight for the first/second animation is 100/0 and shifts linearly until the end of the first animation to 0/100. See the illustration below:


This blending method can be used to blend from the end frame of one animation to the beginning frame of the next animation.


Half a second proves to be a good value for most blending operations, but you can choose whatever size (= blending time) you want.





此混合方法在两个动画彼此重叠时自动生效,这种混合会影响动画交叉的整个部分,第二个动画的“权重”会朝相交的末端平稳增长,在第二个动画开始的时候,第一个/第二个动画的权重是 100/0,然后进行线性变化,直到在第一个动画的末端是 0/100 。请参阅下面的插图:



此混合方法可用于将一个动画的末端帧和下一个动画的开始帧混合。若要启用,必须将第一个动画的 "Blend Gap" 选项设置成“是”。这也使系统能够混合一些东西,从而在两个动画间保持一个间距(故名)。半秒钟对于大部分混合操作而言是最佳值,但是您可以选择您想要的任何大小(即混合时间)。
