How do you calculate square root with nodes? I'm creating my own merge functions in the compositor, but I've run into a bit of a wall. How do you calculate the square root with nodes? Would one have to write a python node to do this? If so, what would that look like?
The square root of x equals x^.5, so use a math node set to Power and put the value whose square root you want in the upper socket, and set the lower value to .5.
