dotXSI files coming out from the 3dsMAX Crosswalk exporter have the
following setup:
handRotation: 1 (SI_RIGHT_HANDED)
xAxis: 0 (SI_RIGHT)
yAxis: 5 (SI_OUT)
zAxis: 2 (SI_UP)
I don't really follow how this would be mapped to XSI's right-handed
coordinate system. Z and Y are flipped with each other. It's basically
telling me to take the Y value and replace it with Z, but keep the sign
unchanged (because it matches XSI's right-handed system).
Is this how I should interpret these values? Obviously the way above
produces a mesh that is flipped around the XY plane in XSI.
I can ofcourse detect the case specifically and adjust it as required, but I
thought the whole idea of having such a flexible template is to allow for
modular coordinate system conversions (as opposed to having a template that
says: Using MAX coordinates, using XSI coordinates, or using blah's
coordinates).
