How to create more terraces than 128? [Help]

I’m making a macro that acts as a previewer for minecraft, so I can preview the result in world machine instead of tediously importing it into minecraft every time.
I need a way to split the terrain into more than 128 segments, and I’ve tried multiple terrace devices in series but it doesn’t work.

If you have the solution that would be great! :smiley:

EDIT: For clarification I am attempting to recreate HYLK’s macro.

For those wanting to help, the effect he is looking after is of a new macro I’m developing, see this Twitter thread for images and more info!
