That link has much good advice but unfortunately doesn’t help when it comes to the special problem of not moving around the subject looking inward, but being inside the subject (a domestic-size room) and looking outward.
Especially when a lot of what’s seen is flat plaster (featureless in 2D) and smooth extruded shapes (featureless in 1D). I get round that by pinning little ‘rosebuds’ (scrumples of patterned wrapping paper) to flat walls and extruded door frames, which allows photos to quite easily register together as single Component (for my purpose it doesn’t matter that the ‘rosebuds’ appear in the textured model).
But even that doesn’t work to get me through open doorways so that two rooms simply register as a single Component https://support.capturingreality.com/hc/en-us/community/posts/360009260331 .
