@Oats(View Post) I tested your hypothesis by spawning a circle of metal (22° C) into the ambient heat world. No heat from it was transferred. Seems like the background is just drawn darker to make it easier to differentiate between object and world? :O
Thank you boxmein it would seem that you are right. I just tested it too and when a piece of metl or brck is cooled to 18° C in ambient heat, it re-heats to 22.
