Models don't look right

[LeleleleMAXIMUM]

joining all the pieces messes the textures up if the textures are chopped up in pieces as well. only do what Roxas358 says if your texture image is just one whole image for everything. and then you'd have to delete the existing Materials before you make a new one for the new object...

he is right about getting it upright, though. just make sure you're in edit mode to make it permanent.
