And not just width. I made this in CityEngine. The distribution map was done by mapping a radial gradient, the Orientation was done by using the plot orientation to a gray value, and the scaleX and scaleY maps were done in a similar way (plot sx to drive grey, plot sy to drive grey). I'd therefore like to use them to fit a distribution object to the Plots. In the provided maps, the min scale is 100% / 1m and the max is 4000% / 40m. Orientation drives the Z rotation.
