Sverchok UV coordinates

sfgst · July 29, 2020, 11:15pm

Hi,

Does anyone know how to generate UV coordinates on a mesh created with Sverchok?
So, not objects created in Blender and then used in Sverchok, but actually created directly in the nodes and then output as BMesh.
For example, say I have a simple plane. Can I generate some simple UVs on it, like a planar projection or anything like that?

Thanks!

There are a few new nodes that maybe can be used for this : https://github.com/nortikin/sverchok/blob/master/docs/nodes/object_nodes/set_custom_uv_map.rst

Follow active quads
===================

Functionality
-------------
The Follow Active Quads node takes the selected faces and lays them out by following continuous face loops,
even if the mesh face is irregularly-shaped. Note that it does not respect the image size, so you may have
to scale them all down a bit to fit the image area. Also it ignores any faces with number of edges unequal 4.

**Note:**

Please note that it is the shape of the active quad in UV space that is being followed, not its shape in 3D space.
To get a clean 90-degree unwrap make sure the active quad is a rectangle in UV space before using `Follow active quad`.
If active face does not have UV map, in case when UV vertices and UV faces was not connected to the node
or all UV coordinate have X and Y equal 0, than unwrapping are created automatically.
Default unwrapping is quad with sides equal 1.
