That message means you need to increase Config.maxPolysVisible. If you don't, you won't be able to see all the polygons in your scene (models will look distorted). Just read the output messages and add up how may polys are being loaded for your models. Use that to calculate what Config.maxPolysVisible should be. When you figure that number out, put this somewhere near the beginning of your program:
Config.maxPolysVisible = 10000 // <----- Some number here
