Hi. Please read this and try it out.
Flat/regular surfaces without features cannot be tracked , no matter how expensive the scanner. you have to make some features (from official markers for marker mode to small stuff you have lying around like lego bricks) on and/or around the object . For Range these shouldn’t be more than 8cm apart. you try to make several scans that way but placing these features in new scan on other places than in the scan before. in the post process you cut these features out and get holes where in other scan you don’t have them and then you merge these scans to a complete one.
Let us know how it worked for you.
