Hi,
Is it possible to mark vertices/polygons in Blender or any other 3D software and detect them in three js while iterating the vertices array from the attributes?
In Blenderās glTF export addon, thereās an option to include āLoose Pointsā. Any points not attached to a face will be exported separately, and come into three.js in a THREE.Points object. Maybe thatās what you want?
You could also assign additional vertex color or UV maps to points, and set their values to something identifiable, but that may be more difficult.
Note than 1 vertex in Blender will be āsplitā at export if it is shared by faces with different normals or UVs. You can disable normals and UVs at export if you donāt need them, to avoid that.

Cool, Iāll try your proposed solution.
Thanks
