No, we do not have demo versions of templates. The reason for that is the fact that there aren't any safe ways to create properly protected DEMO versions of Motion templates.

In case of CineStudio, we offer a 14-day free, no-watermark, no-render-limits trial for each plan. All plugins are included in the free trial, but expansion packs for mTracker 3D are available only in paid plans (they are clearly marked as Not available in trial on all products list).
