Rescale Grid Channel – Rescales the output values of a Grid Channel to a certain range. The colors you get from the Grid Texture can be meaningful when data that is read from the Simulator is in the 0-1 range. But in case the grid data is negative, the Grid Texture will return black color, or if the data has very large values, like e.g. the Grid Speed which can go up to several hundred, the color returned by the Grid Texture will be pure white. In such cases this data should be rescaled to meaningful color values, which usually means rescaling it to the 0-1 range. 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. If you are familiar with the Phoenix channel ranges, you can directly set the Color Scale and Color Offset to the values you desire.
