i tried to create a realistic light bulbs but it is not simple.
the filament of the light don't make luminosity, why?

another thing, who can help me using the emission tab?
i would like to use lumen and not watt, can be possible?

any comment is useful.

Something similar has been post already here by me and I see the engine still need the new kernel in order to have the desired effect which in your (our) case is a glare effect

i find this picture quite excellent ( exept the ground bump texture).
Very unusual, surely surrealist! ( because of the incandescence without light emmiting... )

yes, it is similar to your image, it is true.
i didn't see before... we have the same problem.. octane cannot make anything to be more realistic with the bulb at the moment.

i hope in future very close!!

it is a surrealistic scene as no energy to turn on the light, but i thought that could be an interesting scene.

i hope too the adding of glow/glare and volumetrics.
i asked these features on a preview topic, abstrax answersed it was planned to add these ( glow/glare but no answer for volumetrics).
Isn't it a way actually, with emitting objects and gradient transparencies ?
Hope your bulbs will be enlighted !

i hope we will soon receive a good news!!

Hello,
I am typing from blackberry, do forgive my being short. If no one has gotten incandescence to work yet I have some good news. I did it using hdr textures! Am using version1.022. Only one I have access to. I use portable bitmap file(format) with multiple levels inside I constructed inside photoshop. Half decent results. When I try to amp it up very far I get oodles of weird colors (light doesn't travel very far) but it does travel! I'm not very familiar w/ making hdr files from scratch, but I'm on my way there. If you try it I think you will be happy, at least with light bulb filament. Gradients work too. If anyone is interested it will write up a tutorial. I think this may be a moot point though as I have seen renders with multiple lights in them. I am not familiar with this process. I will research later. I'm so happy I figured this out on my own.
