Models don't look right

[AlucFahhT]

In the menu on the left is the options Smooth and Flat. You want to choose Smooth.

If it still doesn't look right, you will want to go into "Edit Mode". Make sure the whole model is selected and choose the "Remove Doubles" from the list on the left.

None of that worked, it was still blocky and the adding texture made it black. Also, when i remove doubles, it just lets me select one spot on it and stretch it out and deform the model.
