Issue on Raytracing Reflection of enlighten lampshade (subsurface material)

Does anyone experienced in raytracing know why the glass does not reflect the lampshade correctly? The scene was baked, raytracing only for reflection and transluency. Lampshade material is two-side subsurface, with one stationary pointlight inside.

thanks, the light was baked to texture, works like a charm :slight_smile:
