I have 6 layers in a comp, and I'm taking them across, via copy/paste, to another comp. Each second layer is an Alpha channel for the one below it. However when they're pasted into the next comp they ALWAYS are reversed, or randomly resorted, ruining everything about their blends and alpha relationships with one another.
Why does After Effects do this? Is there a way to prevent it from happening?
This doesn't just happen in this instance, I've noticed it nearly always happening when pasting multiple layers.
Is there ANY conceivable benefit to this happening, ever?
Layers are pasted in the order they are selected. Select the top layer first then shift select the bottom and they will paste in the same order. Select the bottom layer first and then shift select the top and the layer order will be reversed. Ctrl/Cmnd + select layers in any order and they will be pasted in that order.
Lets assume you have layers in this order. Red, White, Blue.
Select Red then shift select Blue, copy and paste and you'll get Red White Blue.
Selec Blue then shift select Red, copy and paste and you'll get Blue White Red.
Ctrl/Cmnd + select White, Red, and Bluae, copy and paste and yo'll get White Red Blue
