This document is meant to be a guide. It assumes the reader has knowledge of, and experience in, building real-time environments with Multigen. This work was done at the CCAD at the University of Iowa. If two arms are, remember to build and texture one before duplicating and mirroring it to make the other. However still create the layout below for the entire intersection before you start.
Ranges work most efficiently when the polygons they control are in the same region.
Lay out a few polygons that represent the basic dimensions of the intersection. Make sure that all the dimensions are as specified. The person drawing the spec quite possibly made a mathematical error. Remember the drawing isn't necessarily to scale, don't measure lines. They should if your calculations were correct from step one.
