Description of UV Generation parameters

[JustAndreww]

Is there any description available for these options in menu?

Is it safe to change these options or should I mostly leave them unchanged?

There's some documentation in xatlas.h.

The weights, max threshold and max iterations are used by the chart growing algorithm. You would need to understand how it works and it isn't simple to explain. Even then, tweaking the values doesn't radically improve the resulting charts - the defaults are fine.

Mostly the options are there for completeness / testing and shouldn't be changed.

OK, thanks for the information! That's indeed the hard task to explain how this work :)

If I may jump in here, I would like to ask if the max boundary length and max chart area are in pixels or model space? Thanks

Model space, since they're chart options. PackOptions::maxChartSize is the pixel equivalent of "Max chart area" (except it's a dimension, not an area).
