So recently, I have been noticing neon light blue lines on objects I import, in place of the the normal orange selection lines. Maybe I was supposed to be getting this variant of line before hand or maybe I just somehow haven't noticed it till now. But assumptions aside, I'm wondering what this line is for and how can I get rid of the light blue lines? Also Along with this my objects that are imported seem to have their faces turn from gray to white.
This means in Shading/UVs those edges have been marked as Sharp:
The Sharp mark is used by the split normals and the Edge Split modifier, which are part of the smoothing or customized shading techniques. As seams, it is a property of edges, and these operators set or unset it for selected ones.
As for clearing sharp edges, open up the Edge menu (CtrlE) and select Clear Sharp:
In 2.7 versions, this can be done here from the Tool Panel T > Shading:
But this UI doesn't appear to be supremely intuitive (October 2015). it seems you have to click Sharp first before that panel becomes visible.
Here's a script that lets you
- Mark selected edges as sharp
- Or remove sharp status of a set of selected edges
Code for Object Mode:
import bpy obj = bpy.context.object for e in obj.data.edges: if e.select: # invert current state e.use_edge_sharp = (not e.use_edge_sharp)
