Hello guys,

Here is a simple scene i made a while ago.
The only light source is the strings.
I made four to show difference exposers, iso and camera filters.

It was a over night render.

Time:11.21 Hours
Pathtracing
GTX 580
2K downscaled

something is wrong with your glass

it's refracting like it's filled with glass

its acting like a lens..
maybe using a thin layer of glass would help- with low IOR..
good concept btw..

Yeah, the glass was a quick slap stick specular put on.
and i will add more glare to the strings next time around.

cheers

yes that's the problem, that was already mentioned a couple of times, everything inside the light bulb acts like its filled with glass, that's probably why we need a thin glass shader..
but you have to add another layer inside the light bulb like in real life so it has a thin glass layer.. or change the IOR to soemthing really low.. I know i've been testing out lights inside orbs to get diffuse lights, it's tricky, octane needs more fancy effects for that

Cheers, the render will be improved the next time around

Something similar was posted by me a while ago rising the issue of emitting the wire correctly (glow) like in a real bulb and I see that the new kernel still need to address the issue

p.s. 11hours? 2XGTX580 ?? seems a very long time to me...
