Make heat shields capable of failing, and make ablator depletion matter. Simply.
See user README for details.
To compile, make sure you have MonoDevelop installed then
xbuild /p:Configuration=Release
or open the project in MonoDevelop and "rebuild all".
Then copy ImprovedAblator/bin/Release/GameData/ImprovedAblator to your KSP's GameData.
Start the game. Watch the firey death.
No pre-built packages yet.
I'm looking at how to automate with Travis CI but there are obvious legal concerns with the KSP assemblies.
