How can we store hard edges? XSI does not seem to export edges marked as “hard”. Actually unwelding polygons (real open edge) is not an option. Are there example objects which might help?
This kind of stuff:
Just use appropriate normals to get the look you’re going for. For example to describe the corner of a cube, you don’t want one position with one normal that points away from the center of the cube. You want one position and three different normals, and each of the three faces should use the same position with a different normal to get a “hard edge” look. This is very easy to describe in Collada. Or if I’m mistaken about what you’re asking for, just let me know.
Thanks sthomas, indeed normals was the way to go.
