Why does my imported model have missing faces or holes?

With the release of Skimp 2.0, the chances of missing faces occurring when importing a model are greatly reduced compared to previous versions. However, the following information is provided in the rare case where an imported model will have missing faces.

Models Created at Tiny Scale

Missing faces can occur when importing a model that was originally created at a very small scale.

For example, some OBJ files have vertex data that look like this:

v -3.4101800e-003 1.3031957e-001 2.1754370e-002
v -8.1719160e-002 1.5250145e-001 2.9656090e-002
v -3.0543480e-002 1.2477885e-001 1.0983400e-003

Vertices that have coordinates with very tiny numbers are a problem because SketchUp has built-in limitations that will not allow a face to be created if it is extremely small. 

When importing a such model, you may get a result that looks like this:

To fix this issue, try importing the model using 'meters' as the unit.  This will greatly reduce the chances of missing faces.

If that doesn't work, then you will need to open the model using another application (such as Blender, or 3ds Max) and scale up the size of the model.  If you then save the model again as an OBJ or FBX, Skimp should now be able to import it without any holes.

Merge Coplanar Faces

In rare cases, when coplanar faces are merged, some faces may get inadvertently deleted.  If this is a problem in one of your models, we recommend disabling the 'merge coplanar faces' setting in Skimp.
