Global Temperature calculator

hello every one. i am absolutely new with unreal engine.
I am trying to create a variable temperature for every single object in my project based on the type of the object and if its near to fire or ice or etc… and also check if its in shadow or not.
i wanted to know can i calculate all object’s temp with a single blueprint? or i should create a blueprint for every single object?
i wanted to Tag my objects based on the type of them and set a starting temperature to the object based on the tag. but idk how to do it.
would you explain for me?

BluePrints are really useless if you are new(as you said) better go learn c++ first then start unreal engine with coding not using blueprints… no way to do that with blueprints … if you want to learn c++ W3Schools and GeeksforGeeks would help you
