Light Bulb problem

Anthony · Post by **Anthony** » Sun Mar 18, 2007 6:46 pm

I am having problems rendering a lamp with a lightbulb. All I am getting is this. This is an aerial view because I was trying to see whether it was illuminating anything inside the lamp. I think it might be something to do with it automatically setting the exposure but I am not sure how to change it manually

Strange...
make sure your bulb glass is double sided, with correct normals.
Try Rendering the scene with an external light so we can see what's going on!

Hmmmm now you can't actually see the bulb but what is strange is that you can't see the light emitting fibre mesh either. There is supposed to be orange glass but you cant really see it and I want to know how to make it less transparent but yet again I don't know how.

PS this is from a different angle

i think is scale problem......the light react strange...

Or else add a ground plane? Maybe the light is bouncing off the lamp and into oblivion

Just in case: absorbtion is the contrary of transparency, so the higher the value the more opaque it is. And I second what neepneep says, putting things in vaccum is not a good setup, it's likely the shadow terminators will compute for ever...

Where is this "Absorbtion" you speak of

Grrrrr again you can't see the fibre, you also can't see the glass but on the ground plane there is orange so it is definitely emitting. This is with not extra lights.

looks like MLT is turned off

Anthony, can you please give the version of Indigo and exporter you are using, and also do you hand edit xml's or not ? This is important since Indigo has changed these last months and not all exporters support all features.

The Absorbtion I'm talking about is a tag of your glass material in the xml.

I use 0.6 test 6 blender exporter thats all I know with 0.6 test 6

And I don't hand edit stuff cause I don't know how. By the way those other renders weren't the final renders they were screwy cause I didn't render them for long but there is still a problem because I can't see the light emitter through the glass which is weird. I don't really care if I get my lamp finished cause I'm not really working on it now but still something weird is going on

Has the glass of the bulb thickness?

You have to model glass physically correct like a solid object in indigo to work correctly? So you have to extrude the whole glass part of the bulb to give it a thickness. Also check for correct directions of normals afterwards!

Looks cool

Yup the bulb has thickness. Grrr Stupid Lamp. I know I'll go into the materials and make the bullb 100percent transparent.
