I like how it has many different features that can be used to create animations for your model, such as creating light effects or adding moving elements (like smoke).
The only thing i dislike about this program would have been if there was an option of exporting in other formats than.stl files which could then also work well outside twin motion's app store! Make sure you get familiarized first by watching some tutorials online so its easy enough once u know what each feature does/what buttons do etc.. It takes quite awhile before starting out but when using all these tools together makes things easier since they are already set up from previous projects done previously so no need to learn everything over again at least not yet anyway :).
