Add a nice warm ochre glow to extremely dark rooms with the combination of 3 different types of light. This book is a nice decorative addition for those who prefer to add something pretty and discrete to their chat room. The effect is mostly noticeable in very dark rooms with ambient on. The effect is not noticeable in rooms without ambient.
Feel free to play with the results and the book placement. Possibilities are endless

Light colour cant be changed by you, but if you are interested in a different lighting colour or this type of effect on a different mesh, please send me a note and I can see what can we do.
