Having problems with models after importing them from SketchUp?

Questions & Answers
1

Hello everyone,

So I got into 3D modelling and after looking around I settled on using SketchUp. I learned the basics and started making some models. I made a small coffee table and a TV on a stand. I exported the models as .fbx and imported them into Unity. I dropped them into my scene but I had some problems:

  1. The models are really small and I have to use the scale tool to make them big. Any reason to this?
  2. The models are weird and missing certain parts. For example, my coffee table is fine with the textures when looking from the top, but when you look under it is all transparent? My TV and Stand model has all missing pieces.

You can have a look at these pictures of what happens:

If anyone can help out, it will be greatly appreciated. Thank you!

I’m unfamiliar with sketchup built in tools, so I don’t know if you can fix the problem in there.
The problem you have is the polygon normals are not facing the direction you want them to.

2 options here - either flip the normals so they face the direction you desire. Or (only for table) model the table with actual two sides for the top part. In other words - make the top part of the table a cube/box instead of a flat poly plane with no backside.

There is a 3rd expensive option - in Unity you can apply a double sided material. This isn’t really a fix, and is not the optimal choice.
