Animation with an Object appearing and Disappearing using Boolean Modifier

Question

I'm working on creating an animation involving the boolean modifier in Blender as show below. I'm happy with how the animation looks in Blender, but when I try to export the animation to Unity, it doesn't work the way I intended.

I created the animation by moving the arrow's location on the x axis, using an array modifier to create a total of 3 arrows, and using a boolean modifier set to intersect to only display the arrows between two planes.

I've determined that the problem is that the boolean modifier is applied at frame 1 in the exported animation, which means that the two visible arrows just move as shown in the second gif.

Does anyone have advice on how to handle this situation?

Seeing as your animation is barely longer than 20 frames, you could export 20 different models and in unity create a prefab which animates their visibility. — Leander, Jul 17 '19 at 12:53

@Leander This is better than anything I've come up with, but I was hoping for a solution that could work for longer animations in the future, too. — BroDudeIII, Jul 17 '19 at 14:06
@DuarteFarrajotaRamos My question had nothing to do with materials. Is there a part of that answer that I missed? — BroDudeIII, Jul 17 '19 at 14:06
I think Duarte misunderstood. For longer animations, Im guessing you will have to implement the boolean operation in unity. Looks like someone has managed to do so for the editor. There is no way Blender C coded boolean modifier will be ported in an fbx. — Leander, Jul 17 '19 at 14:09
There is, see part "Same applies for many other features specific to applications (...)" — Duarte Farrajota Ramos, Jul 17 '19 at 14:09
