Hasta La Motion!

I’m working on a very complex script on a very long shot, and despite nodes being totally transparent or hidden behind masks that are out of the timeline, I’m seeing the node tree light up almost everywhere almost all the time. The only exception is when I’ve used a merge node and mixed a layer to zero. Generally I don’t want to sully my merge nodes with time-specific elements – I’d rather keep time separate – or I am using non-merge nodes to combine layers and still need to turn them off at some point. In AE, I’d simply set the layer in and out points and that’d be the end of it. Since Nuke doesn’t show time, I want to use separate time nodes also so I can label them with the frame ranges. Is there any other way to do this? Anyone have preferred methods that can be placed on a single connector?

Thanks!
