Hi Gal Davidson
change the DETECTOR SENSITIVITY from HIGH to MEDIUM ( or even LOW ) and change the max reprojection error from 3 pix to 2pix, align and then reconstruct it again.
Is it possible to see all cameras in the scene ? Do they have proper overlap and so on ?
Regarding the textures, use the UNWRAP tool and set the FIXED TEXEL value and use the OPTIMAL TEXEL ( it is all in the UNWRAP tool ) and then you need to CALCULATE the actual textures, as you probably calculated just the UVs but not the textures…
