<snip>

I have started working on the same problem.  I wanted a really large scene
renderd with POVRAY.  My example can be seen at.

http://www.brickshelf.com/cgi-bin/gallery.cgi?i=217204

It is a full 360 degree view that can be viewed in a panoramic viewer.

The area of the model is 24 baseplates wide by 27 baseplates long.  The
baseplates are grouped int 72 zones, each of which is 3 plates by 3 plates.
Each zone is drawn separately by using L3P and POVRAY.  The 72 images plus
an image for the background were hand combined in a drawing program.  (Image
Composer)

There are some problems with this method.  For example, the palmtree in
front has its shadow cut off.  It fell outside of the 3x3 area.

I rendered each section from a viewing point for the entire scene.  I
rendered the images as tga files so that the background is transparent.
Then, I take all of the images and overlay them in a drawing program that
understands transparency.  It works just like a painted background for a
movie being overlayed on live action.  It's fairly intensive but the result
is cool.

I'm currently writing a program that will automate the rendering and
combining process.  When it's done, I'll make a post.

I only have an 586, 400 mhz, but I wonder if there are any other things that
could help.

My machine is a 300 mhz with 32 meg of memory.  Since I'm never working on
more than a 3x3 section, mlcad does not bog down to much.

Has anyone ever even modelled something this big into one file?

I keep them in separate files so that I could reuse sections.  There is only
one 3x3 section with the trees on them.  I use it over and over in different
places to get the forset look.  Many of the sections of the monorail track
are reused as well.

Does anyone have any tips on doing really large models? I am trying to build a city. I have several buildings built, but when I start adding roads and the separate buildings to the scene, MLCAD bogs down. Even when I turn stud rendering off and go (...)
