Hi Michael,
no, I'm using XSI 7.0.1 and mostly with obj.
XSI still has extremely unflexible handling of user normals (basically you can't change anything on the object after import, otherwise it will no longer render correctly in most cases) and often doesn't like the output of MoI, but most of the times I can fix it to be usable.
That's still my main issue here since the NURBS import (IGES) in XSI is completely unusable - it has massive problems with the accuracy of close-to-the-edge trims... (or could MoI get an inverse-option of the command where it optimizes planes to be closer to their trimming? Un-fit with an offset? But I'm not sure if it would solve the problem anyway, the NURBS implementation in XSI is about 11 years old and untouched since AFAIK...)
I don't know if Autodesk buying Softimage will help in that area, since they announced that XSI is now their game solution - huh?
My other software Lightwave 9.5 now has options for using user normals as well, but it also is a pain as soon as changes on the mesh are needed.
I don't know what else could be done other than extremely involved analysis of the NURBS object to produce a ngon-polymesh where all the borders can be connected so that no user normals are necessary. This is what I nowadays find myself doing by hand ...
Not your fault though ;-)
Best regards,
Thomas Helzle
