It sounds like you are doing things that move objects and/or images from the
directory structure location they had when you loaded them in your scene. If
you do this, you will have to relocate them the FIRST time you reload the
scene--unless you edit the scene file manually (see below).

However, if you do save the scene, it should be able to find the OBJECTS the
next time you load it. The location of the IMAGES (that are part of an
object's surfacing) though, are saved with the object file. Thus, you must
Save All Objects (button on the Objects Panel) before quitting the scene. You
should also do this any time you change the surface of any object.

When you do run into the "missing object" problem, one thing you can do is
edit the scene file manually. For a scene with more than a few objects, this
will be faster.

An example:

If you have a scene that loads objects from your "Smith Wedding" directory,
the lines in the scene file that load the objects might look like this:

LoadObject C:\NEWTEK\OBJECTS\SMITH WEDDING\Heart.lwo

But if you take the Heart.lwo object out of the Smith Wedding directory and
move it to the Jones Wedding directory, LightWave will still look for it in
the Smith Wedding directory the next time you load the scene. It won't know
where it is, so it asks you for it. A similar problem could happen if you
reload the LightWave software.

If you navigate to where the Heart.lwo is, select it, then save the scene,
the scene file would now look something like this:

LoadObject C:\NEWTEK\OBJECTS\JONES WEDDING\Heart.lwo

However, you could have made this change yourself with a text editor before
loading the scene. In that case, LightWave would have looked in the Jones
Wedding directory for the heart--right where you had put it.

Now, for a scene with only a few objects in it, it's probably easier to just
find the objects the first time you reload the scene after moving them. But,
for a scene with 50 objects, this would get, as you note, boring.

So, in a many-object scene, if you move a lot of the objects around while
LightWave isn't looking, just load the scene file in a text editor and change
the lines so they refer to the correct directories. The easiest way to do
this for all references to a given directory would be to use a "search and
replace" feature.

A word of caution though, save a copy of the scene file before you mess with
it. That way, if it gets totally messed up, you can just go back to the safe
copy.
