This may not exactly be what you’re after, but the beauty of raytraced
images is that they can be whatever you want them to be, and they are an
order of magnitude better in quality than those produced by the other
programs you mention. With the right settings you can create instructions
that are pretty close to those produced by Lego®.
Here’s one of my
attempts. These images are straight out of LPub with no post processing
How would you like yours to look? Perhaps we can help.

Wow, I am surprised. That is the kind of thing I’m looking for... what kinds
of settings do I need to change for that?

The thing is, I lost all the files associated with creating those instructions,
so I have no record of the exact settings. I’ve got another model almost ready
for instructionfying. I’ll let you know when I find them myself. I recommend
‘Virtual Lego’ for learning this stuff.
In the meantime, here’s the gist: Use megapov to render the edges. Place the
lights carefully. To get a nice contrast between horizontal and vertical spaces,
place at least one light directly overhead. If you want an orthographic view,
don’t turn on the ‘orthographic view’ button. Use a very small field of view
instead. The instructions linked above used 10°. This ensures that all images
and parts images come out to the same scale. (this last one may be a bug in LPub
that has, or soon will be, fixed - try both)
And most importantly, keep doing test renders until you’ve got it exactly how
you want it, even if it takes a hundred. These images only take a few seconds
each to actually render, and you’ll know if it’s right after the first one.
