'throwingSparks' uniform bool & damage from hull heat

[Griff]

A tiny little cosmetic bug.
I think the bindable shader uniform 'throwingSparks' doesn't toggle properly when you take a lot of damage from excessive hull heat when flying into a sun or through a planets atmosphere.
If you manage to escape in time before you explode the bool doesn't go back to false even if your shields & energy charge back to maximum. Also no sparks come out of the ship when the bool is true.

It's not all bad news though - it all works properly if you use guns to shoot a ship into it's throwingSparks state - sparks come out and the bool toggles to true, as the ship recovers the sparks stop and the uniform bool toggles back to false - this just doesn't happen when the damage is caused by hull heat, the bool toggles to true, not sparks come out and the bool never toggles back to false.
