How to add custom lighting in nodes

[CrisisConsciousness]

Using graph.lights().split (0,2) blocks the light sources in threejs, but wants to add new multiple light sources to the node, so that the nodes are affected by the intensity of the light sources and produce shadows.
May I ask how to put light sources into the Geometry of Mesh in nodeThreeObject? Currently, it has been found that all light source positions are not in the node, but have been initialized at the (0,0,0) position
