Meshroom -> Room best settings

[CommanderPaladin]

Hello, I need a little help. I'm trying for a week to find the best settings for a room with less needed modifications of the mesh map (in Blender) for holes and missing parts.

I used NIKON D5300 for the pictures, I have around 200 pictures of the room, but I always get holes, or even missing entire regions.
If I place half of my photos (for example only half of my room) the results it's better, but if I try the entire room at once, sometimes I didn't even get a mesh map, only some random points, even if in 3D viewer shows the good positions of the camera.

All I would like to know it's a tutorial or someone who can show me around on how to properly do the software part of the process.

I tried the same things with others apps, and they give me wonderful default results with minimal modification needed for the mesh map, but this is because I don't properly know how to use Meshroom and I cannot find a proper room tutorial. I'm really in love with Meshroom and I don't want to change it because I have used it for small objects and it worked wonderful, bonus, it's free.

I did pictures and pictures over and over, modified the Meshroom settings but I still cannot get a decent result.
I really don't know what to do anymore, what tutorials to follow.
For small objects it works flawlessly.

Thanks you so much in advance.
