One of the most useful features added to RealityCapture is the “Cut by Box” cropping functionality. It allows you to cut away the marginal triangles of the reconstruction box.

In RealityScan, although it includes a “cropping” functionality, the feature just changes the reconstruction region’s shape rather than actually cropping the meshed model. Meaning, it reconstruct the model once again with those marginal triangles that you’re trying to get rid of.

This mean, every export out of RealityScan has marginal triangles that are untextured (which I’d always crop out). You cannot export a non-water tight model out of RealityScan.

My feature request is: Include a real cropping functionality either by simply filtering the triangles outside of the box or by using RC’s “cut by box” remeshing feature.
