It's 1am, and I googled every outdated site on the net, I give up.
In 2.79 I had a code:
mesh = bpy.data.meshes.new(mesh_nev)
mesh.uv_textures.new()
...
mesh.uv_textures[0].data[i].image = meshhez_tartozo_texturak[textúraindex]
...
mesh.uv_layers[0].data[o * 3].uv = (u,v)
what is no longer working for me in 2.81 and I find no good info on the net how I can do this right now. Can someone please help me out?
Thank you!
That code worked in 2.79?
Please when posting code in future make sure you leave in all relevant lines. eg in question what is o, i, u, v
Very little difference between this answer and the following, real toss up between answering and closing as duplicate, which I'll leave for others. Quicker to answer and hence confirm in 2.82.
Get/Set coordinates for UV vertices using Python
Add uv_layer to mesh, add uv-coords, with python
Add a new layer (same). Notice if a new layer is added, but there is an existing layer, it will not be index 0. Will be the last, or easier keep the reference returned.
>>> me.uv_layers.new(
new()
UVLoopLayers.new(name="UVMap", do_init=True)
Add a UV map layer to Mesh
get or set the active layer, it can be None a gotcha in answers to links above.
>>> me.uv_layers.active
bpy.data.meshes['Cube'].uv_layers["UVMap"]
>>> me.uv_layers.active = None
Silly example adds random UV (a scribbly mess) to each UV
import bpy
from random import random
context = bpy.context
ob = context.object
me = ob.data
uvlayer = me.uv_layers.new() # default naem and do_init
me.uv_layers.active = uvlayer
for face in me.polygons:
for vert_idx, loop_idx in zip(face.vertices, face.loop_indices):
uvlayer.data[loop_idx].uv = (random(), random()) # ie UV coord for each face with vert me.vertices[vert_idx]
