Is it possible (through a dll mod or otherwise) to create a building that is impassable but doesn't block temperature from equalizing through it? I have a building type that I don't want Pawns walking through but I don't want it to hermetically seal off rooms either. I've tried doing something like the door does, calculating the average temp of nearby rooms and adjusting the temperature in each to equalize it, but that doesn't work if I put two of these side-by-side. Any ideas?
