* Add radiators * Limit heat transfer to fluid heat capacity * Adjust datafield names * Fix material arbitrage * This code has been debugged, and so there are no more bugs. Debugging code is therefore unnecessary * Adjust radiator layer subfloor visibility * Cache CVars * No default Co-authored-by: metalgearsloth <31366439+metalgearsloth@users.noreply.github.com> * Like and unsubscribe * Fix CVar caching --------- Co-authored-by: metalgearsloth <31366439+metalgearsloth@users.noreply.github.com>
