Thanks for the suggestions. I'll try doing something very sci-fi generic so hex patterns, moire and electricity. I think this should be pretty good for the Asset Store as it fits many different games out there.
@BalanceFiend I will do the breakdown for sure, I just need some time
As for the particles in the intersections. I don't know how to do it efficiently in realtime. I could raytrace against objects here and there but this would not be very precise. The idea seems to be cool tho. This could add a lot to the feeling of the forcefield.
