Can't get light bulb to work

Re: Can't get light bulb to work
Maybe the specular is too high and it's reflecting the black background? Try making it a glossy transparent material and lowering the specular value.
Don't know if you've tried this, just an Idea.

Re: Can't get light bulb to work
What "specular" value are you talking about ?

Re: Can't get light bulb to work
I always called exponent...exponent also if you notice....Also, I tried glossy with an exponent/specular of 500 and it didn't fix it. So i switched it back to specular transparent (like on the screenshot).Godzilla wrote:Specular=exponent and visa versa... I thought?

Re: Can't get light bulb to work
Silly question but your not using Reinhard tone mapping are you?

Re: Can't get light bulb to work
well maybe the light from the filament is making everything else go dark? if that was a real bulb the filament would be burning out. Maybe tried camera tone mapping?
Just a suggestion

Re: Can't get light bulb to work
Tried both Camera & Linear tonemapping and it did not have any positive effect

If it's not confidential any chance you could post the blender file?

Re: Can't get light bulb to work
K downloaded it - quick look and can't see anything obviously wrong. Will take a closer look later

Hi, Borgleader!
This is what I've got from your scene. But I had to:
-make the lamp smaller
-apply the scale
-apply all the modifiers
-after applying the modifiers remove doubles
-recalculate normals outside
-change the tungsten filament emission from 1500lm to 15000lm (because I think that the glass is too thick)
-put the lamp inside the cube (with flipped inside normals)
But still it seems to be a bit strange
blendfile
Edit: I was wrong with the filament emission. After change to another tonemapping than Reinhard it became nuclear

Re: Can't get light bulb to work
OK I've had a longer play and... I haven't a clue
I thought it was just an exposure problem and so used camera tone and cranked the emitter material all the way up but it's still not right. The glass is picking up the colour from your back ground but it should be more transparent and affected by the emitter.
Your setup and all the materials seem ok to me, though I'm far from and expert - though thinking about it I didn't check the scale.
I think this is one for Ono or one of the other 'experts' here on this forum

Re: Can't get light bulb to work
I tweaked the model and some of the materials for you.
Hope this was the result you were looking for
