In typical Swift 3D fashion, Electric Rain has crafted a way to easily
define surface groups, and apply materials and textures to it. This highly
requested feature will finally allow you to make that six sided cube with a different
materials on each side. But don't stop there, this feature will allow you to
make some incredible detailed models with life-like texture qualities.
Simply select a group of polygons by dragging your mouse over the region
and mark it as a surface group by clicking on the "Group Selection" button
in the Surface groups property panel; then drag your desired material from the
material gallery onto the surface area. Done!
