I changed versions of the 121 to 125 and there were problems with the modification of vertices in THREE.BoxGeometry

Hello, I switched to version 125 and I get errors when trying to modify, e.g.
cube_geom.faces [0] .materialIndex = tex_px;
After looking at what’s in BoxGeometry now, it turns out that there is no such thing as faces.

Now how do I modify materialIndex and how to disable faces.
In 121 I did something like this:
cube_geom.faces.splice (a, 2);
cube_geom.faceVertexUvs [0] .splice (a, 2);

Starting from r125 Geometry has been removed and replaced everywhere with BufferGeometry (all [Shape]Geometry are now producing BufferGeometry instances.)

To modify faces / vertices / normals you should now modify the buffers.

So I understand that to make a cube I have to add to this:
const vertices = new Float32Array ([
-1.0, -1.0, 1.0,
1.0, -1.0, 1.0,
1.0, 1.0, 1.0,

1.0, 1.0, 1.0,
-1.0, 1.0, 1.0,
-1.0, -1.0, 1.0,

the other 10 vertices?
And write down:
geometry.setAttribute (‘position’, new THREE.BufferAttribute (vertices, 3));
Speed up the buffer geometry solution?
Because I do not know whether to stay with version 125?

I noticed that this library changes very often, there is no consistency in its design.

It doesn’t look like this has been answered, but what’s the new solution to splice one of the faces from a geometry?
I couldn’t find anything in the links provided above.
