Glass Mat is rendered black
Hi,
I modelled a light bulb in Cinema, used Glass Material and in Indigo the renders became black. Don't know why :/.
The rendered images look kind of that.
I already tried Optimizing-function, because i got a list of triangle errors. Afterwards I didn't got those errors again in the log. Next idea was pre-converting. Same black render again...
Perhaps it helps to be able to take a look in the .c4d, so you can download it here.
used sw: Cinema 4D 10 , Indigo 1.1.10 & Cindigo 1.1.10

There are some issues, first you have the bulb as a solid glass which is no good, second you have black as absorption meaning that it will absorb lots light therefore rendering it black, third some reversed normals, four the light itself has too much power, five check the size of the lamp to correspond with real life values, six check global scale so the scee conform to real units.
Suggestions, 1) create a thin glass, 2) turn absorption till full white and play from there, 3) turn the gain down

for me absorption was written as absortion would be written as heard, at least in my native language the fact this typo existed is due to the fact that I missed the s and abortion is a correct written word. Still, abortion is just a word, don't gave it any more importance then it deserves... (then there's the fact that chrome eats little letters for breakfast )second you have black as absorption meaning that it will absorb

Yes of course. Just forgot it.PureSpider wrote:Juniorsatan wrote:and sry for asking question # 43785372
May we see a pic of your scene being all fine now?
In fact, I rendered a lot of images, but the most noise-free images are
and
As soon as I tried to emit light from the conductor (by using light layers), the entire scene went black. Except for some caustics or the like. Don't know why (second time! )

Junior, it works quite well for me, with render layers:

There are 4 emitters in that scene: 3 large softboxes @ 100 watts each, and the filament @ a much higher level - 1000 or 2000.
Thanks to light layers, you can adjust the relative intensity of all the lights [which is all you'll be doing with Reinhard tonemapping anyway] without having to rerender.
