From the example images you provided I can tell you right away that you need to take a lot more pictures to get any decent result at all.
Ideally you want to circle around the object and take a picture every 10 to 15 degrees at multiple heights.
Also, I do recommend using a tripod or at the very least a monopod to prevent blurry pictures.
Try to keep your ISO level as low as possible, also try going for a decent depth of field, preferrably setting your cameras F-stop somewhere around 8 to 10.
At 15° between photos and five different heights per position you will end up with about 120 photos.
That amount should allow the software to come up with a decent alignment even for slightly reflective objects.
Of course, more = better.
You need to take enough photos for the software to somewhat reliably create a single component during alignment, or if you get multiple, the vast majority of the photos (>90%) should be assigned to one component.
Free For All Example Project (Trial version Only!) provides an example on how to approach this.
