Unsolved Is there a way to export mesh roads into dae objects?

I tried the "export selected as collada" option but it seems to export a blank file? with every object, in game it appears invisible with 0 polygons and i cant import it into blender

 

You need to import it into blender with a template, it should look like this.

The object name needs to have a "_a200" for example or any number after.

Tutorial with a template you can download in the description.

 

I've done it before, I'm sure. Maybe double check with some 'normal' objects to make sure it's working properly. Otherwise, you can right click the object in the scene tree and export from there I think. Maybe that will work..
