Temp./Dens./Fuel/Burn Emission Mode

There are two ways how channel values (temperature, density, fuel) are added to the fluid


the object will emit the value set below per second


the channel values for the object will be held constant the value set below

To understand the difference, think about temperature. Using Set mode, you specify the temperature the object has. Using Add mode, you specify by how much the object will heat up the fluid every second. In the later case, if the fluid wouldn't carry away the heat around the object (e.g. Buoyancy is 0), it will continue to heat up the fluid infinitely. While in Set mode the value stays constant.


The value emitted per second (in Add mode) or to be set constant at the object (in Set mode).
