Combine children problems

When I import my FBX models created by sketchup into unity I end up with tons of meshes. I can usually go into sketchup and explode the models but sometimes this causes errors on import such as there being no model at all within the FBX. It is a peculiar problem but exploding all of my models isn’t ideal any how.

So I have been trying to combine children within my models, the only problem is that it doesn’t seem to combine the children under sub children if that makes since? Either that or it maxes out on how many meshes it can combine.

I have attached some screen shots so you cans ee more of whats going on here because explaining it is just too hard.


Any more thoughts than zero?

Are you using the CombineChildren component in Unity (menu: Component > Mesh > Combine Children) or combining the meshes yourself with SketchUp?

Ive tried combining the meshes myself in sketchup by exploding the models but many times this boggs down sketchup and the FBX exports are corrupt, or at least they don’t come through on the Unity side. So now I have been trying to combine meshes with the unity script and the screen shots above show the problems I am having with this.
