No, there are no folders or groups in After Effects. It is one of the most requested features (from where I'm sitting) for After Effects.
After Effects allows you to Precompose layers. So, lets say you animate your 25 individual raindrops, and then you want to change the colour of the raindrops from blue to green. You COULD apply a colour correction filter to each raindrop layer. But you could also precompose (or "nest") those layers into their own composition. The pre comp is a single layer in your main composition, which you can then apply the filter to just once. You can still edit the raindrops individually inside their pre comp.
A frequently requested feature, known as "uber twirl", would allow you to twirl(expand) a pre comp open inside a main comp to edit each individual layer without leaving the main timeline. We live in hope!
Don't forget to post your feature requests to the AE team. It's a popularity contest - the most popular requests are the most likely to make it into future versions.
Sweet, i will try that out!
Thanks dude, u are today's hero!
The pre-comp is not only a way to group layers, it is a way to change the rendering order. Pre-composing is a valuable tool in almost any compositing program and invaluable when doing things like dynamic text animations and motion graphics.
Yes, i've tried that out, worked brilliant! Thanks!
