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.

I recommend “LEGO Software Power Tools”, I know the guys that wrote it. :^)

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)
|
LPub guarantees the consistant scale, not L3P or POV-Ray. Without LPub the
images always fill the window (L3P), so the scale would constantly change.
L3P does not have an orthographic option. LPub puts it in for you.
LPub does not let you control the lights. LPub guarantees you shadowless
lights. You do have control over POV-Ray render quality. Lower it to get the
kind of images Allister got. You do not want reflections. Turn off Previous
Parts Color Scaling. Use MEGAPOV to get the edge lines.
| |
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.
