Hello everyone.
Ive never tried to render a scene with a light source coming from a bulb, typcially I only use keyshot for car and motorcycle renders where a simple emissive material is enough.

So If anyone has any advice or experience for me to do this properly i would appreciate it.

I added emissive material to the bulb filiment and created a sphere to use as an area light to cast all of the shadows. However when i added the bulb glass back into the scene the sphere area light got blocked out and lost all of the shadows.

So a quick fix i did two renders. One with out the bulb glass and the other of just the bulb. In photoshop i manipulated to get some kind of result.

I know this isnt correct and im sure there is a proper way to do this so hopefully some one here knows.

1st image is base render
2nd is bulb render
3rd is merged together in photoshop

Thanks in advance
