Final step... Go to FILE/EXPORT, Browse where you want to save your model.
'''YAY Almost done!!!
If you get an error saying "To many vertices in col node".. Select the col model
go to EDIT/OBJECT PROPERTIES/USER DEFINED tab. Type this in the field below. vertLimit=400
EXACTLY like that. Or just copy/paste that.

WOOHOO we are now in Previewer. Click file NEW, locate your box model. Then click the MATERIAL, notice the name of the material you gave it in Gmax. Click that, then locate your texture.

FINALLY we can submit, But dont submit it. Unless you want too. So thats it. You now have enough knowledge for gmax to get you on your way. I hope these tutorials were helpful. Again if you have any questions feel free to contact me in world or Email me.
