Having worked with the mesh editor extensively for the last couple months, I
have this observation: The more changes I make to the mesh *without saving*,
the more likely it is to crash. The crash always occurrs right after
clicking on the render button, and I know immediately that it's happening
because the hourglass remains on the screen. Then I get the Windows xp
notice that the program is shutting down. So now I try to click the save
button every time before I render, which does prevent the problem, but if I
get on a roll and forget for a while, oh, the agony! Perhaps this problem
should be looked into?
Now the question. Is it not possible to add a primitive or mesh object to a
mesh and make it part of the original mesh? This would make life so much
easier if it were. I've tried every which-way to do it, with no success. Am
I asking for the impossible?

Hi Steve Shelby, you recently wrote in moray.win:

Really?? Hmmm. Have you noticed any specific pattern, or is it only
when you hit render?
I've worked for hours on end without saving and it's never crashed for
me. But I don't render, that often, either.

Also, before Moray exports to POV-Ray and renders, it saves the
current scene in a file called rendering.mdl. So if it crashes during
rendering or export, that file should contain the scene right before
rendering.
I'd certainly like to look into it. The next time it happens, maybe
you can send me the rendering.mld file that it saves, I might be able
to reproduce it.....

Yes, it is. You can use Copy and Paste in the mesh editor to do that.
You just have to make sure that you're in Face mode. Then select some
or all faces, press Ctrl-C and then Ctrl-V as often as you like. Note
that the faces will be copied into exactly the same place and will be
selected, so it seems as if the screen doesn't change. But if you use
Translation mode to move the faces away, you'll see you're actually
moving the duplicates....

You can also edit one mesh object, copy some faces, exit the mesh
editor, select another mesh object, go into mesh editing mode and
paste it there.... just make sure you don't press Ctrl-C (Copy) in the
non-mesh-editing mode, since the mesh editors won't paste primitives.

Only when I hit render.

Maybe it's just my computer.

I was not aware of that. That would save a lot of heartbreak.

I hope I don't have to do that, but if it happens again, I will. ;^}>

That I knew, done it many times, although I discovered the hard way that
when pasting, it has to be in add or toggle mode, or the pasted faces are
irretrievable.

I could have sworn I had tried that already, but apparently not, because it
works! I just found that I could even create a primitive in the same file,
convert it to mesh, copy it in the mesh editor, delete it, and then paste it
back in mesh editor. This will save a lot of trouble in the future. I wish I
had asked about this a long time ago.
Thank you,
Steve Shelby
