The point cloud creation process only works with points, not planes.

You're options include:
Hole filling/editing the mesh either in Photoscan or an external program.. remeshing or retopology
Making the surface more amenable to photogrammetry (e.g. dusting with powder/ matte spray)

I thought about dulling spray. But it's a mess (and a mess to clean). Much easier would be to create geometry in the photos (in a way, also masking that area of photos to be ignored!) have the rest processed as DSM and then rejoined as a mesh. Very quick operation for areas like this, windows, etc...

Except SFM doesn't work like that. You could try to retopolgise in another application like 3DCoat and then re-import for texture.

Hello!

I can really recommend that you try using noise projection if you have access to a projector.

We use it a lot for tough surfaces without inherent features that Photoscan can use for reconstruction.

You can also easily take a texture pass by changing the projected image to a black one and use flash or other lightsource.

I've attached an image as an example. It is of a polished mens shoe which was completely shiny and should be quite similar to the tiles and sink in your example except being black in colour.

Best, Magnus.

Magnus,

Can you provide more details about how you do these things? Thanks
