visual and numeric representation of what each node doing in pixel and value processors.

Thank you for your reply.    Copying functions or parts of pixel processor  into value processor is a good advice.

Still it's a kind of inconvenient .  

So to be specific what I am asking are:

1.  2d viewport has normalize button. I am working with floating point math and it shows nothing most of a time .

2. both pixel and value processor shows output of any selected node , a picture  or numbers  or a list  of numbers

'Please do something with it.'

Hi

It is not very clear what you are asking for.

In a Substance Graph you can double click any node and its output will be shown in the 2D View

In a function graph, you can copy your function into a value processor node which will display the ouput that you set as the output node. Once you understand it then you can copy the function to where you want to use it.

The pixel processor just runs the same function for every pixel in the input image, so again you can set the 2D view to the Pixel processor node whilst you test adjust the functions. You can also test your function by substituting image sampling nodes by fixed values and testing it, or elements of it, in a value processsor
