Unity thermal camera for built in RP
Took the idea from here and made some modifications.
Clone this repo into
ThermalCameraScript to your camera and hook up the resource references (mouse hover each property to see details)
For any heat emissive object, add
TemperatureController to it and set its temperature (manually or with script) (Again mouse over the property for details).
When the game is running, press space to toggle between normal view and thermal vision. Or edit
Update() in ThermalCameraScript.cs to set up your own toggle.
