@OsirisTheVileyou miss the point of my question, it shouldn´t throw a shadow (as far as I know) and I understand that the blade is a model in the game.
But for in-universe it either depends on the blade being plasma, thus matter that can throw shadows in theory, or it being laser, which is more plausible in canon since it has been frequently adressed as such, not only in different translations of Star Wars e.g. "Laserschwert" in german or "sabre laser" in french, but also in english.
And since laser is basicly light, it cannot throw a shadow.
If the devs said that this was implemented intentionally, that would be totally fine by me, I only want to know.
I love that we're getting into the science. 🙂
There are canon sources indicating that lightsaber blades have weight to them, which implies mass, something else light doesn't have. There has also been testing of laser-plasma interactions which could allow a laser to act as an aid to the containment of plasma and essentially keep the blade "flowing" (which would help to explain some of the pulsing and other effects in unstable blades in TFU and other Star Wars games). This also ties into the lore about Kylo Ren's saber needing the crossguard due to cracks in the kyber crystal, requiring heat to be vented through side channels. The secondary "venting" blades could plausibly be shorter because the plasma they're releasing isn't being accelerated by a "guide" laser like the primary blade is.
