This tool lets you get a bit more insight into what is happening under the hood of XSI’s rendertree. Using it as a intermediate node, it will display all the data that passes through it in a way similar to how Photoshop Levels is shown. It will also show you the number of times the shader has been evaluated, as well as displaying the minimum and maximum range (which is dead handy for setting up commonly used nodes such as Change Range and Gradient Mixer).
