我的三维房间

Model a small diorama room in Blender and bake three separate lightmaps: neutral daylight, night, and a single lamp contribution. Load all three as textures on one ShaderMaterial and mix them in the fragment shader with uniforms such as nightMix and lampStrength, multiplying the lamp layer by a tint color. Use a VideoTexture on the monitor mesh for life, and restrict OrbitControls to a narrow azimuth range with damping so the composition always reads well.
