The biggest issue with this set up is the light through the glass bulb is not as bright, however I do love that it actually makes the light bulb more defined! Lovely contrast between the bulb and lamp
One way to fix this, is to disable ray length entirely from my node group. The node group will then ONLY displays light from the filament inside the bulb and does not cast noise into the scene, then the bulb and lamp will be illuminated by the point light more evenly. Try setting Ray Length to 0 and see what you think! (inside the download)
This is of course not a perfect solution, but I was amazed how the final result were so efficient without needing compositing, and we can:
1. Light the scene with very minimal fireflies and very little noise
2. Decide how bright the filament should be
3. Decide how bright the inside of the lamp should be
4. Control the light into the scene independently from the bulb
5. More easily control the glare from the filament
Side note, light linking the emission object to just the bulb does not work. Light linking only works for the first direct bounce, all other indirect bounces can still cast onto other objects, this include fireflies and noise.
If you can get a more noise free image with this much adjustability and with as little as 64 samples then I'd love to hear!
