Lighting bulb material

Guys, i'm playing with night interior scene here... Main light for the bar area using difuse light material each [ behind the bottle rack and on top of bar table ]

Other source of light is 6 decorative bulb light on the right of the scene.. The bulb is modelled and have thickness [ i grab the bulb model from 3d warehouse though, ] and put small box painted with difuse light material too. The main problem is that the bulb get illuminated by the small box inside it,but the light itself wont speard out and illuminated the half right of the scene...

The material itself;
Basic material is shiny plastic grab from plastic material pack
I add translucent sloton layer 0 [ mate / phong ] with white color [ 87% ]

Any suggest for this case please?
I want the bulb emitting the scene too, not only the bulb..


Regards'
Iwan W.

Have you enabled caustics for photon mapping? Or try render with MLT or MLT/BPT. Also it might be worth to try point lights, specially if you use biased rendering.

I think you should put a box over each bulb. give the box a light material

but make sure that the material is hidden. this way you can control the light

better and you wont see the box.

Ok, i try this solution

1. Use the translucent plastic from
2.Change the lighting solution from box with difuse light material to point light ..

Rought render using mlt/BPT on laptop [ULV core2duo 1,3Ghz] for 45 minutes, 24 phase and still grainy, but i'm satisfied with the result curently.. Going to cook it tomorow on PC :)


The strange thing is that if i turn on volume lighting, the result will be similiar with the pics i post first, while if volume lighting tur off i get the result i want.... [ Alex instruction is to turn on the volume lighting if the material have VL suffix, and this plastic material have it.. ]
