OBJ file problem, number of vertices

Can anyone explain about the vertices of the obj file? 

I made a 3d obj file using RC. Then I open it using notepad. (attached file image)

In there I found there are 6 rows of vertices numbers (attached file image), but it seems there should be three. 

If anyone has some idea, please tell me.

Thanks in advance.

Hello,

in the last threee columns RGB values are stored, i.e. color of each vertex. You can disable exorting vertex color in the Export model table by changing Export vertex colors to False.

Thank you very much Zuzana Ďuríčková CR. I got the point. 

But If I export model by changing Export vertex colors to False, then is it possible to get a coloured 3D model later??

Thanks again.

Yes. Its called Textures.
