Many people have problems when they import there sketchup 3ds into no limits. Something that looks like this
"Black faces"
There is a simple, yet effective way to get rid of these.
1.Import your object into anim8tor
2.Click the 4 balls (that represent objects!)
3.You will notice how the object's material is a base color and is dark.
4.Double click the material ball and you will se that 'Ambient' color is dark...
5.To fix this, simply click the "=" sign for all materials that face this problem, then export properly.
Hope this fix's that problem,
