Sounded like Mark wanted to, for example, have a Blur node set to 5, 10,
20, 30, them average the results.. without having to copy the node a
bunch of times
There's no built-in way to do this, but.. I wonder if this is doable by
having a plugin which contains two inputs:
First input is an image. Second input is where you connect some node.
The plugin would internally make a bunch of copies of the node
connected, then for each of the nodes set a knob to a specific value
(maybe like the Wedge node in Houdini). Then when the plugin is
rendered, it just merges all the internal nodes together
(over/average/min/max/etc)
Actually, it would easily prototyped as a Group, with a callback script
which sets-up the internal copies plus the merge.

Hi Mark,
Although you can accomplish this in python that shouldn't be necessary.
It would probably be simpler and more flexible to just use a TCL
expression in the nodes values. This way you are not creating generated
curves and unnecessarily adding tons of data to your script.
For example if your base value was one and you wanted to increase it by
.1 per frame over time the following expression would do.
.9+ frame/10
You can also use the rand, sin, and cos, functions to add variation.
If you needed this to be the same in many nodes you could just drop it
in a NoOp and expression link it where needed, or use python to
propagate it throughout your script.
Best,
Erin
