Hello,
as a matter of fact, the DynamicShaddow Cast does not work well if at all. It was buggy from the beginning and it could be, as mikey117us recalls, it was disabled with version 1.4.b.
Since I usually use original Ubi files as templates for my own fikles, I simply keep those controllers and the related nodes and, since it does take much effort, add them to new items, just in case ...
In summary, there is absolutely no good reason to keep these nodes or add them to new models. On the other hand, they do no harm
