CRMC is a good idea in extreme pressure environments, since its melting temperature increases with pressure (more pressure, less melting). A good substitute for CRMC could be QRTZ/TUNG with a few TTAN pixels. Basicly 1 TTAN pixel every 3 pixels (TTAN, QRTZ, QRTZ, QRTZ, TTAN....) with a tmp of 1 ( !set tmp ttan 1 ) will block pressure and prevent QRTZ/TUNG from breaking, and if PTCT/NTCT is put behind that QRTZ/TUNG + TTAN layer, it will prevent TTAN from melting.
(Let's say you have a single PTCT/NTCT particle at 2000C, it will melt and might get blown away, which in time will damage the shield and reduce it's particle count (and efficiency).
In that case, I'd say you can do a pretty ok heat shield using mostly PTCT/NTCT, these two material cool down at a rate of 2.5C per frame, the more you have, the better. The shape you're using spreads the heat to the whole surface, which is better than an "aerodynamic" shape that would have the least contact with the heat. This is because when a PTCT/NTCT particle touches [hot particle], the more neighbouring PTCT/NTCT particle it has, the better it will cool down.
I layered a bunch of different materials because I can't tell which one is the best
Why did you use the elements you used in the heatshield (what's the purpose of each of them)? I think I already know but I just want to make sure so I can give accurate feedback
cts mean Comment Too Short. thats what it means.
I think "cts" means "comment too short", but I didn't look it up so it's not certain
