Thanks,
I’ve done this and it’s fine, however, it would be quicker to just select a part and rerun in high detail etc. I don’t want to reduce the size of the overall reconstructed area, I just want to be able to rerun high detail and texture of the smaller parts at highest resolution. For example create normal detail model colorised and untextured (all parts) but do high detail or full texture individual parts that I can then open up all parts (normal and high) together in other software. By changing reconstruction area you have to then do multiple reconstructions, which have already been done as parts. Also the parts seem to be randomly placed throughout the model. It would be good to have them next to one another in a sequence so bits can be deleted afterwards. Just a thought.
