You didn't calibrate, that's the wat. If you follow the tutorial, you'll see that you have to check the "calibrate" checkbox, then choose 6 vertices from the 3D object and place it at the right place in the output, then it will transform the 3D object perperly to fit the real world object.
Agree with Gilbert. Would be great to just adjust the 4 corners of the models bounding box just like a normal layer to align the object to a reference image. Any tips anyone?
That's about the same than 4 points, except that you can choose which points of your model you want to position, and we request a minimum of 6 points mapped for a good calibration.
Hope that's clear
