Rescale Grid Channel – Rescales the output values of a Grid Channel to a certain range. Rescaling You can find out more info about the Phoenix Grid Channel Ranges here. Rescaling using this helper simply measures the data range of the selected Channel and changes the Color Scale and Color Offset options. This means that if you simulate or load a new cache sequence in the Simulator, you will need to do this rescaling again to make sure the Grid Texture values are still in the Min-Max range. Rendering channels such as the Fire Color and Smoke Color/Opacity cannot be rescaled. Rescaling is especially useful when you are reading channels such as Channel Speed or Channel Temperature which can range up to several hundred or thousand, and you want to use them as color or opacity, so you need to scale them down between 0-1, which would require you to set a very small Color Scale multiplier.
