How to make textures wrap around imported objects?

If I import a sphere for instance from sketchup via. playup into unity the texture I apply is always "broken" at the edges. The sphere unity has as a preset object you can use will draw textures correctly. When I want to import unique shapes I've made in sketchup or make a "sky-sphere" by reversing the faces of a sphere in sketchup I run into this problem.

 

I'm wondering if anyone can offer insight on this issue yet?

 

You need to learn how to unwrap your objects. A 3d model has no sense of how to wrap a texture around it, so you need to define this (The UV set, which is each vertex position in the uv layout).
So... google Unwrapping.

 

Here is a very good explanation and a how to using blender.

I've so far partially figured it out after looking at the article. I will get a fuller understanding of it in time. Thanks
