Bug #4903
Heat shield does not explode when it runs out of ablator.
100%
Description
version is 1.0.2, but that isn't in the list yet.
Apparently it needs to overheat as well, but that should be happening at this speed and altitude: https://youtu.be/reNelOD60pI?t=120

Can confirm this. Apart from not exploding, the heat shield does not conduct heat towards the parts attached to it, making everything occluded by it, pretty much 100% heat resistant.

Note: convectionVelocityExponent set to 3.35 for increased heat (to ablate all the ablator resource). Clean install with mods used: Visual, KER, HyperEdit

Updated by The shield's max temp is 3400. Your part temperature won't exceed your velocity once you run out of ablator. (not taking into account certain physics settings like the velocity exponent)
Assuming stock settings, there's no way the shield will explode at that speed and altitude. That said, a part maxTemp of 3400 is a little excessive. I don't think even Apollo's shield got quite that hot (5000F = 3033K) and that was 5x faster than what you're doing there.
It might make sense for both shield maxTemp and conductivity to be lowered and raised respectively after the ablator runs out, though in DJK's video, by the time he's run out of ablator, he's pretty much decelerated to where it's survivable.

Sorry, this is correct behavior for the heat shield.
