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 somet…

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.Buffer…

[image] Qjr: cube_geom.faces.splice (a, 2); 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.

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