I honestly don’t know what up with this, I mean, I checked to make sure it wasn’t overlapping so please help.
It’s the stuff in the back tail of the sub I was trying to make
They do look a lot like overlapping faces.
In Edit mode select all and W -> Remove Doubles.
In Edit mode with nothing selected hover the mouse over a part of the model not near thee tail and press L. Move the selection to see if there are duplicate faces.
If that doesn’t help post up the .blend.
weird, the remove double thing worked perfectly. Sweet
