Displacement mesh capture wish.

In PS you'd likely have to (java)script it, i'd think.
I don't know of any command able to retrieve the max value in an image.
Once that was done, you'd need to add a layer with that value of white (1800 or so in your case) and then set it to divide the image below.
I am unsure the ops would work in 32pobc, though, it's really the wrong app for this stuff.
Maybe give Fusion a try?

I'll get a trial of Nuke and see if I can figure it out....might be back here in a while when my brain begins to
react from an overexposure to maths

Although of course the whole exercise may be moot unless there is a fix for the vrmesh output.

Luckily I do have the terrain all set up for the project using the 2d approach with the raw file, which also works perfectly well in World Machine, plus your info was still extremely useful in
clarifying a few things that will be of use.

Ahah, it's a lot harder to describe, and read, than it is to perform.
It's a scaling operation, think of it this way.

So far I got this input but on rendering get an error, which is unintelligible to me, so could relate to an error in how I set it up or some trial limitation.
How do the settings look to you?

It looks ok, as a flow.
I've attached you my comp, feel free to open it (or copy all the text in it and paste it in nuke.) to check the setup for the various nodes.
