Value Processor
In: Atomic Nodes
Complex
Since version 2019.1.0
Description
The Value Processor allows you to execute a custom function for a one or more Values, that is returned as Value output, on an optional input.It works with the new system of Values being accessible inside the compositing Graph since version 2019.1.0. It is comparable to a Pixel Processor, with the difference that it does not compute a function for every pixel, but rather a single value values or textures plugged into it.
Parameters
- Value Processor Function:
Allows you to access the internal function editor.
Usage Guide
This is not a full description on how to use the Value Processor, it's best to refer to Functions and Values in Substance compositing graphs. Some specifics for the Value Processor are pointed out here instead.
Sampling an input.
It is possible to sample an input just like in a Pixel Processor. The main difference is that the $pos System Variable is not available, as you are not parallell processing any pixels and there is no "current position".
Us a static Float 2 instead:
Outputs
You can only have one single output in a Value Processor (by right-clicking > Set as Output), as with Functions everywhere else. If you want a single node that returns multiple Values, you will have to create a Sub-Graph for it with as many Value Processors as you want.
