Same lights. Different rules.

A NodeMaterial’s surface graph is only half the story. Keep the same geometry, color nodes, and light rig, then swap the lighting model or narrow the material’s light list to see which part of the result changed.

Intensity and light motion update the active light data without rebuilding the material.

MeshStandardNodeMaterial keeps its physical lighting model and evaluates the scene-wide light list.

The official ToonLightingModel quantizes direct irradiance through a gradient map. Use ?forceWebGL=1 to compile the same NodeMaterial lighting paths through WebGL2.
