Aloha
So I wanted to create a look of a light inside an object and have the light illuminate the object from inside and also illuminate the scene around the object.
To test I took the stock figure object and put an omni light inside it with area shadows and some falloff. I then took a cylinder and scaled it up so the figure was inside. I then added a basic material with the SSS shader effect in the luminance chanel and applied it to the figure object, choosing the apple preset.
I did a physical render and it was pretty much what I was looking for (see attached image). The object was clearly being light from inside and also some light was getting outside the object and lighting the large cylinder.
So I turned off the figure model, added a platonic, positioned it so the same light was inside and then dragged the same sss material that was on the figure model to the platonic. Hit render and boom.... total black scene.
I tried several other objects with the same result, black scene. The only object this illumination from inside using the sss shader I can make it work on is the figure model....So is there something special about the figure model or am I just being dumb? :) any help appreciated.
Find attached an image of the figure and cylinder being lit successfully.
