I don´t know if it is even possible, but it would much improve collisions. Beams with collision would be able to collide with other beams, triangles and with static level objects.
It MIGHT be possible, but you would have to have every beam have a ton of nodes on it (as the nodes impact most of the deformation), but creating all these nodes would have major performance strain. Colliding with the beams themselves is not currently possible.
I know that beams currently can´t collide. I´m just saying that it could be implemented in game engine so you don´t need tons of nodes, just set {"collision":true} for beams.
Currently, the engine implements node-triangle collisions for performance reasons. Beam-beam collisions is in research phase right now. I cannot give you any timeline for it (or even say if it can be done), as implementing beam-beam collisions both efficiently and physically correct is a very hard problem.
