LDraw snapshots coming up empty

[Ber]

So you can see the model and rotate it, but when it comes time to do the snapshot it doesn't show in the file.

What options are checked in the "save snapshot" dialog window? (where you enter the image name)

Yes, that's right, in the LDView window I can see and rotate the model.

At the moment in the Save Snapshot dialog I have none of the checkboxes selected.

I have tried with these turned on, in various combinations:
- Save snapshot series (file name then ends in 01)
- Don't use Pixel Buffer
- Transparent background
- Auto-crop
- Save image with specific size

The output file is always 100% black / transparent for any combination of these options I have tried.

I tried saving as a jpg once (still black), otherwise always saving as png.

I have not tried the checkbox 'All Steps'.
