Hi pafurijaz, thanks for testing it! It is not really expected that such a highly detailed and heavy mesh would give a manageable result, it would need to be significantly simplified for that.

The main focus of the converter is to give a highly accurate result, it's really more intended to enable getting a smooth and accurate conversion from a light sub-d cage so that can be used as a base shape for further NURBS modeling.

Conversion of 3D scanned data really needs a more specialized tool that is focused entirely on that process, it is not a specific focus area of MoI's converter.

That being said it is good to see some "torture testing" of it as well!
