Hey Folks! Busy day today, as I shored-up the spark vfx and integrated it with repair actions in-game.
Early in the day, I finished tweaking the spark vfx to use the correct lens flare sprite, increased spark speed, and disabled collisions. The collisions were causing problems any time the AI was too close or turned in such a way that the vfx intersected a nearby object. And for how subtle the bouncing particles was, it wasn't worth fixing.
Once that was done, it was time to add it to the game.
