When I combine a heightfield with mesh2 object, it crashes Moray. Sometimes
it renders it just fine, and I can work with it for a while, but eventually
it always crashes, and when I re-open the scene, most or all of it is lost,
even though it was saved before it crashed. Is this a bug or what?

Seeing as it crashes, yes it's a bug.

What do you mean by 'combining' a mesh and a heightfield? Can you give
me a step-by-step procedure to reproduce this?

Lutz,
I was going to say csg or intersection or difference, but I just tried
something that makes it look like a mesh and heightfield can't even be in
the same scene together. I found the .bak file for one of the scenes that
was ruined before (when Moray crashed, it deleted the mesh, the lights, and
the camera from the scene) and found that in the .bak file everything was
still there. I had not yet created a csg, so the mesh and the heightfield
are sharing space, but not combined in any way.
The other scene I was working on has a mesh and the same heightfield,
combined as a csg. This is the one that caused the crash. I can open it, but
if  I click on the csg in the select tab. Moray quits, giving me this
message: "Moray v3.5 for windows has encountered a problem and needs to
close. We are sorry for the inconvenience."
I just tried re-creating a csg again. I opened a new scene, pasted the mesh
object, and used merge object to get the heightfield. I created a csg and
added the heightfield and the mesh. When I tried to render it, Moray
crashed, giving me the same message. If I even try to open that file, Moray
crashes.

Update: I was overstating when I said you couldn't even have them in the
same scene together. I had saved the first scene, then altered the mesh and
saved it as a different file. when I made the csg, it corrupted both files.
Today I opened the first file (recovered from its .bak file), and combined
the mesh and heightfield as a group. This caused no problems at all. What is
the difference between a group and a union? When I look at the .pov file, it
doesn't call it a group; it calls it a union.

There is no difference... one is a Moray-ism one is a POV-ism. 

I just made the group more lenient in what it can contain (like lights
and cameras). But it's exported as a union, since POV-Ray has no
concept of a 'group' in the Moray sense.

Hi Steve,

thanks for the bug report.

I tracked it down to a plugin problem. It seems that a few plugins
might have this problem and I will be talking to plugin developers
shortly about it.

I reproduced it with the Animation plugin and so I have fixed it for
that plugin and made a new update available from our website..... it
also adds a new experimental feature that some of you might appreciate
:-)

Go to http://www.stmuc.com/moray/meplugin.html for details.

Regards,
