在AE CS 5 及 CS 6版本以后，Vector Paint 特效被删除了。我查找到了官方的一些解释。
Vector Paint effect: When we ported After Effects to be a 64-bit application, we had to rewrite large parts of just about every feature in the application. This meant that we had to look at each feature and consider whether it was worth the effort of bringing it forward into the next version. Of the relatively small number of features that got left behind, the UI for the Vector Paint effect has been the one that the most people have told us that we should have kept.
See this article for some more context.
So, here’s our question to you: Which parts of the Vector Paint effect do you miss? Is it just the ability to paint in the Composition panel? The ability to wiggle the stroke/path? If you’re going to submit a feature request asking for the functionality of the Vector Paint effect to be brought back, please let us know exactly which pieces are important to you. There are many, many parts of this effect that are redundant with the existing paint tools, shape layers, and other features, and we think that we may be able to satisfy this request by just adding back in the specific features that are still missing, without resurrecting the entire Vector Paint effect–which would be a huge amount of work and would displace much other feature work.
大体是讲将升级至６４位的时候，Vector Paint 特写程序重新书写起来比较麻烦，还有官方认为很多其他特效可以替代该特效，我不这么认为。
