Another way to explain it is like this. When you drag a composition = into another composition - i.e. you have a pre comp - After Effects = normally treats that pre comp as one layer. =20 There is no difference between pre-composing and pre-rendering out a = composition as a quicktime and re-importing it. The collapse transformations switch changes this behaviour so that After = Effects no longer sees the composition as a single layer, but acts as if = all of the layers in the pre-comp were now inside the main composition. = Because After Effects isn't seeing the pre comp as a single layer, = settings such as motion blur don't apply any more - it uses the = individual motion blur settings of all the layers in the pre comp. = Additionally, adjustment layers and blending modes in the pre comp will = now interact with other layers in the main comp. -Chris
