Ah, good to know. 3DS Max, I wouldn´t have thought of that...

I tried most of the things suggested and appreciate all the tips and help. A colleague was in today with his machine and copy of 3DS Max. It was able to read the files and output polygons with correct normals. Curiously, the file sizes for the resulting FBX was much smaller than from Rhino or Maya.

The advantage is that your Normalpass will output useful information, all shaders computing refraction or transparency, subsurface scattering and last but not least reflection will give reliable output... I know, it´s a pita but shading&lighting&comp will be far less error prone. Personally, I´d look into converting to polygons and merging to useful shells. Rhino, MOI, Maya´s convert to polygons. The reason why I suggest to do the clean up/conversion in Maya is that it gives you more options to edit Normals. Just make sure that User Normals and Geometry Normals point into the same direction... Once the geometry is in XSI, nuke the user normals and live with the 30-35° smoothing...

This kind of data often has pretty random normals, and I don't believe Maya shows you bad normals in black like Softimage, so there'd be no way for you to tell unless you turn on the normal vector display.

Client gave me an igs file which I can get imported into Softimage and Maya. The problem is, that in Softimage half of the normals are flipped but it looks great in Maya. The object has hundreds of small parts so it's not effective to go find every last inverted shape manually. Is there a good way to get the NURBS into Softimage or keep the normals from getting screwed up on import?
