How to correctly set parameters using mathematical expressions
Blender has a very convenient ability to set the desired values through mathematical expressions. If we don’t know the exact value, instead of manually calculating it, we can simply enter an expression that will calculate the desired value.

Executing operators with parameters
When making your own custom operators, sometimes it is necessary to pass them certain values – execute operator with parameters.
The passed parameter must be defined as an operator property.
Transfer selection from the UV-map to mesh
The UV-map is directly linked to the mesh through meshloops. We can use that to transfer the selection from the UV-map to the mesh.
To transfer the selection from the UV-map to the mesh, we need to cycle through the mesh polygons, check which meshloops are selected and select the corresponding vertices on the mesh itself.
Nodevember
Nodevember is a monthly challenge you invited to make procedural objects for Blender every day. It can be a material, a shader, an object, anything, if only it would be procedural. “If you can call it nodes, you can call it Nodevember!”

How to get vertices from Vertex Group by its name
To get a list of vertices from the vertex group by its name we can use the following code:
|
1 2 |
[vert for vert in bpy.context.object.data.vertices if bpy.context.object.vertex_groups['vertex_group_name'].index in [i.group for i in vert.groups]] # [bpy.data.meshes['Cube'].vertices[0], bpy.data.meshes['Cube'].vertices[1], ... |
