Hello, I want to know how to change the duration of items, such as the flame left by heater. I want it to exist all the time without disappearing.

Hello, you want to edit the file 185: Data.Global_itemSpt. Look for the actionGroup 42, with the name property having the value "gfire". Then edit the property ite_lifeTime. If you set the value to 0 it will last forever. Some lifetimes are 0 but not forever (such as yellowcol) because of the fspec: -1 in their last frame. Thanks to @不饿白帝BEBD for teaching.
