Hello,
how can I get crease and bevel weight value for selected edge via Python?
What I need exist in N panel Item tab
but there is no tool-tip with python code.
Asked here but seems they have no clue what I’m talking about (I need to see value, not to change).
Yes, that script was useful, currently it look like this:
For some reason it can’t set Crease and Weight value on new object edge/s. Only after I manually add Crease mark on some edge it start to change values on all other edges, the same for Bevel Weight.
It seem, when I manually add mark, it add some data to the object and after then I only can modify it with this script
To the point.
I need something like this:
Code
import bpy, bmesh
from bpy.types import Panel, Operator, Menu

bl_info = {
