you could lower the environment light and up the exposure but it won't render very efficiently...

Grazie beppe and Thanks radiance, I understand the new kernel is getting closer to be released is it? unless this 'feature' is in the pipeline, still good to know about it.

I'll wait impatiently..

Hi, I had put it in the Ressources and Sharing section :

I hope that you will find it useful. in my example, the filament is a simple cube, as I had not to show it. But the effect is the same.

Well, I have done many trials with double enveloppe (glass with thickness), simple enveloppe, with external invisible enveloppe emitting light. Images below : Ist image with thick glass (double enveloppe)
Second image with thin glass (single enveloppe). I used mixed materials : Specular and diffuse invisible emitting materials.

There is no light source other than the bulb enveloppe and the filament, and I always get a shadow under the bulb, in the middle of the area, where should be the max of intensity...

I also encounter weird artifacts (rectangular blocks) on the top of the image. They are independent of the angle of view... Very strange.

Now real do a pretty look lightbulb? (:

It is look nice, but if add glass


:'(

thx (:

Just an idea,
Maybe you can make the inside of the glass a different material than the outside and make that more
reflective (and still transparant) maybe that causes light inside to flow around more?
Just would be the first thing i'd try.
