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.

To enable it, you have to set the "Blend Gap" option of the FIRST animation to true. Also for the system to be able to actually blend something you need to keep a gap (hence the name) between both animations.

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)。
