Hello Ken, Sorry for such a late reply. AFAIU and some old experience with STVDS, the approach is by date, i.e., you need a map per date. This is because of the snapshot logic of STDS. I remember having done animations with vector time series, but again, that was a long time ago. Have you tried calling the list of vector maps instead of the stvds? At least to understand if it is a temporal or spatial topology issue.
There was also a QGIS plugin by Soeren to visually explore STDS ( https://www.youtube.com/watch?v=xxHt3jJbnYw), and IIUC the time manager of QGIS required only a vector file with a date field to show animations.
