I am never good at lighting but now I’m creating a light bulb. Here is what I get:
This looks too stupid, the light bulb is plain white.
Here is the node for the glass material of the bulb:
And I placed a point light with default setting inside the bulb.
How can I improve the lighting? What have I missed?
Many Thanks for the help

Try something along these lines, it’s not the best but I gave it a shot.
In this case it’s loosely off how a light bulb works, technically a globe is transparent, with a bit of the glare coming from both our own eyes, and any smudges/dust on the globe. Hence its basically a transparent material with a slightly rough glass.
Hey, I tried your setup and it looks lot better!
I’m post the result in focused critique after render.
Thanx for the help !!
