Hi,
The viewport in Reality Capture has a limit of one 16k texture. Please try to take a render of that view.
If it still doesn’t look right please check the quality of your texture by clicking on your model, and check the texture is at least 100% (doesn’t need to be more).
If not please unwrap your model using fixed texel size set to optimal:
then re-texture
If you would like to disable the outer cameras for texturing, I would select the inner ones you do want for texturing, then invert the selection and then disable the outer ones for texturing.
but hopefully this will not be necessary after following the previous steps.
