What am I allowed to do with the Twinmotion free trial?
The Twinmotion trial is freely available for anyone to use for an unlimited period of time for testing the product; it may not be used for commercial purposes. The trial includes the full features of Twinmotion, with the exception of exports being limited to a 2K resolution.

Seems that is better than nothing for new hobbyist! ;)
