2-make the light bulb as dosen't cast any shadow
3-the highlight inside the light bulb looks weird to me :)

Hi there,

can anyone gave me some hints to make a "bulb" shader in Maya (MR)?
I should do a panel with a lot of bulbs and I like to get a look like the "frosted" bulbs.

If I try to use a misss_fast_shader I have to place a point light at every bulb, did I?

Any tips would be nice :)

I think I remember seeing some properties in the mia_material that will help you with a light bulb. You will find an explanation on it in the help docs. I remember seeing that. Right click on the mia_material in hypershade and click the "mia_material help". Scroll to the bottom of the help. i don't have access to maya right now. So I can't confirm it. I might be wrong

I don't think using SSS on light bulbs in any kind of array would be very wise or efficient. It's a lot of extra math and calc time that shouldn't be necessary, except under dire artistic circumstances.

I think if you simply use mia_material_x for your glass, and start with the Frosted Glass preset, you should go pretty far. Work with the translucence to either map in (as a texture) your color and fuzziness, or let the blurry reflections/refractions sample it in at an added render-time cost.

If you're going for multiple lights, a simple texture map would likely be fastest in my opinion. You'd still use one light for each bulb if you want accurate shadows, or you could use a high-scaled Final Gather effect to emit FG light from the surface geometry itself, instead, which can create some really nice, soft lighting effects.

@all:

thanks for your time and the hints :)
I've got received a mail from Rachel and he did it with just a simple phong-shader, a little bit glow and an Environment Sky.
Works nice for me :)

Thank you for your help! Take care,

Would you mind to show us how the final result looks like?.

Thank's.

@joie:

Yes of course would I show it.
However, my client had a "new" idea and so I don't need the bulb anymore. The whole concept is braaaaand! new....
This means I stopped working on it. Sorry....
