Is there some sort of tutorial for formula somewhere? I can only deduce how to use it from the tooltips from the editor, but not enough to learn it from the tooltips alone. How do I create more complex formulas? Like add then multiply? Do I have to store the result of the formula setting into a variable then create a new node that will multiply the variable? If that's the case then I will have to repeatedly use the Store Formula Value node. Insights? Thanks !
