I extruded a curve and the result has the right geometry but the shadows appear wrongly on the flat surface. How/what do I have to adjust to correct it? I already checked for duplicate vertices.
Since the Auto Smooth option is not available for curves at the moment, you can do the following to get sharp(er) edges with a smoothed surface:
- Use the EdgeSplit Modifier to get sharp, unbeveled edges. The default settings should be fine, but you can set the Edge Angle to something higher close to 90°, since you only want to bevel the border edges.
- For beveled edges, use the Bevel Modifier, set Width Type > Percent (that seemed to be the only width type where you don't need a high number of segments, but might depend on the curve's U/V resolution). Set values for Percent and Segments according to your liking.
