Are there any techniques to save me from processing nodes that are not resultant in the output, like a pull render system?
Imagine I have a generator like a noise image being driven by current frame, that then goes into some image filters individually like mirror, color effects etc. and I want to switch between each, ie just noise, noise with mirror, noise with color, with a "get items from list" .
If I do this, all of the nodes will be processing even though theyre not selected and their output is going nowhere.
The received line just appears to return a carriage return. When I turn on event viewing I can see an event on the output port but the port itself tells me that none events have occurred. I've got it all being refreshed every frame etc. does anyone have an example?
