I've got a script that draws a bunch of individual items onto the same object, and I need to generate a UV map for each item right after it's drawn before moving on to the next one.
My current code seems to me like it should work, because the individual instructions work great when I run them via the console, but when I run them as a script, three of the instructions (
bpy.ops.uv.unwrap()) don't seem to do anything.
Can anyone help point out what I am overlooking? Thanks in advance!
Here is a simplified script that can be run on the default cube that basically illustrates what I'm trying to do (it draws a separate plane and tries to unwrap it):
import bpy import bmesh obj = bpy.context.object bm = bmesh.new() bm.from_mesh(obj.data) mesh_verts = bm.verts mesh_faces = bm.faces v1 = mesh_verts.new((2,1,1)) v2 = mesh_verts.new((3,1,1)) v4 = mesh_verts.new((2,2,2)) v3 = mesh_verts.new((3,2,2)) face = mesh_faces.new((v1, v2, v3, v4)) v1 = v4 v2 = v3 v4 = mesh_verts.new((2,3,3)) v3 = mesh_verts.new((3,3,3)) face = mesh_faces.new((v1, v2, v3, v4)) v1 = v4 v2 = v3 v4 = mesh_verts.new((2,4,4)) v3 = mesh_verts.new((3,4,4)) face = mesh_faces.new((v1, v2, v3, v4)) bpy.ops.object.mode_set(mode='EDIT') bpy.ops.mesh.select_mode(type='VERT') bpy.ops.mesh.select_all(action='DESELECT') v4.select_set(True) bm.select_history.add(v4) bpy.ops.mesh.select_linked() bpy.ops.uv.unwrap() bpy.ops.object.mode_set(mode='OBJECT') bm.to_mesh(obj.data)
