This feature is very useful in quite some cases. E.g. to play at locations without Internet access and no pre-cached/transferred content. Or to add the tour as a movie to a playlist. It also allows to create a smooth show even if the computer is not able
to render the content at full frame rate.
Some things I found out while testing the feature:
1. In a tour that moves between planets in the SolarSystem mode, a planet is only shown at the end camera point of a slide.
When coverting this tour into image files, the end camera point is not converted and as a result, the planet is not shown.
Adding a short extra slide brings back the fame containing the planet. Maybe there is a problem when counting the frames (starting from 0 or 1?)
2. Images are not saved to file when selecting the Dome Master option without enabling Full Dome mode in WWT. The progress bar though shows all is working fine. As there is no error message, it takes a bit to figure out the problem.
3. The background of the Dome Master images is white. I suppose black is a better option.
None of these issues are showstoppers.
