Hi, I wonder if anyone can help. I have been trying to create a sort of soft global illumination effect. What I have done is as follows

1. create a hi-res ball from the primitive props
2. export  the ball as an obj file
3. re-import it wwith thenormals reversed.
4. increase the size to 600% to create a large dome
5. remove all other lights and add a point source about half way between the ground and the top of the ball
6. bring in james.
7. switch on raytracing and increase no of bounces to 4
8. render.
9. dissapointing single overhead light effect.
10. change ambient light to 1 and set colour to white.
11. render - no change
12. keeping the point light source in the same position, move dome.
    12 . render - no change
13. add reflectance node to dome
14. render - no change
15. Grrr. What's happening ? why isn't it working ? Where are the subtle light effects I was anticpating ?
