I have a scene with many clones of a complex animated element that I need to export for use in Standalone.

If I have "Render Instances" turned on, or make the Cloner editable (creating instances set to "render instance"), the export will crash just after finishing all frames. I have pulled up the log for octane and the console, but they do not show any errors.

When it crashes, the Orbx export dialog always shows one frame past the end frame i.e. "Export frame:1001 of 1000"

The crash does not happen if I turn off render instances, making it export all the geo which takes up more room in an already large standalone file.

Can anyone shed some light on what might be going on?

It may be very big file and a crash at end.

I think you are right to some degree, but there is something else up.

If I reduce the frame range, I can get it to export. But why does it export fine without instances with a much larger file size?

Somehow plugin can think the mesh of instances get updated on every frames. And write new mesh for every frames. Check it in LV if you see recreation of meshes on every frames.

Here is what I'm seeing in the Log:

I mean Live Viewer. If you see lot of updating process between frames. This may show many changes on meshes and big file at end. Of course i don't have idea about resulted orbx.

Ah, I see.

There doesn't seem to be a lot of updating, but I don't know for sure.

What about a different method for scattering, maybe in Standalone. Is there a way to generate a CSV file for scatter positioning from C4D?

my advice to convert child objects to polygons in cloners with render instances. This will avoid to recreation effect. Another trick is to don't use subdivision surfaces. Use object tag's subdivision to get smaller export files.

I have already converted everything I can to polygons, but I still have some parts that contain Cloners with animation on them.

So what should I do about cloners within cloners?

Not so much to do i think! Best to divide your scene to a few parts to export.
