This is a difficult room to be sure. Everything is against you. Everything is glossy/reflective. Lots of repeating patterns. Light is less than ideal. And its cramped. Basically everything that your told to avoid is in this room.
A couple of tips for better results next time.
Use ISO 100. A lot of the bumpiness in the model is from the camera noise.
Don’t use aperture priority mode. The shutter speed is changing between shots. In one shot the toilet or sink is bright and then higher up with the window or mirror light the camera’s exposure adjusts to the brighter light and the toilet/sink are now very dark. If you was shooting manual the toilet and sink would be the same brightness. Reality Capture is dumb and will think these 2 things are completely different subjects.
White balance is constantly changing. Outside is very blue so it makes the wall by the toilet very yellow to compensate. The light on the ceiling is very pink so auto white balance adds more green, and the light by the mirror is green and again auto white balance is compensating. Each frame looks good by itself but RC is dumb and can’t tell it is the same object if in one frame it is blue green and the next red orange. If you shoot raw you can adjust to one white balance that looks good across the most pictures.
Overlap. It looks like mostly a grid like pass on each wall shooting perpendicular, which is fine. Your scanning method looks good. One place i had a hard time though is finding common control points from one wall to the next. Example: I could only find 3 pictures of the corner that the wall with the door and the wall with the window meet at the top and none at the bottom corner. For this room what would have helped is the diagonal method standing in one corner shooting the opposite. The each wall by its self was covered good, but where they meet was hard for me to find.
I’m sure, with the raw files, I could produce better results.
