Now that I have become more proficient in creating Gmax ground polygons, I want to share the knowledge with others. It took a lot of experimenting, and the information comes from scattered sources, so I want to take the guess work out of making ground polygons.
My first video tutorial, of a series, explains the first step of taking raw imagery and preparing it for use in Gmax.
It involves slicing up the image in to usable tiles, determining image resolution if unknown, creating an appropriately sized plane, and applying the textures.
You can use it for reference in Gmax, or export it as a ground polygon; which would be the "Photo" layer.
Here's the final product created with the tutorial:
