Hi misterdemo,
Is this what you are looking for? This is done by clicking the Tgi3D SU AMorph's "upsample" command a few times depending on the level of detail you want.

Free Training version of Tgi3D SU Amorph will probably not be enough for this unless you want to work in smaller portions each time, but you can download the 30-Day Trial version of Tgi3D SU PHOTOSCAN (another plugin) to try the "upsample" command without vertex limitation. Tgi3D SU PhotoScan includes ALL the capabilities in Tgi3D SU Amorph (and additional features for creating accurate 3D models from photographs.)
