Bom dia!
Tenho me deparado com este problema quando
vou renderizar cenas com taças de vidro.
Configurei o material Template\Common e renderizei
no motor advanced\Alternative_AA\04d_Medium_AA4(ultra).
Como faço para apagar essas manchas pretas? Se eu criar um
material avançado (deep material) posso como evitar isso?
Good Morning!
I have encountered this problem when
i will render this scene with glass bowls.
I set the Template \ Common materials and render with
the engine Advanced \ Alternative_AA \ 04d_Medium_AA4 (ultra)
How do I delete these black stains? If I create a
Deep material, can avoid this problem?

Re: Como tirar manchas pretas de materiais em vidro?
Hello, your light object is intersecting or touching adjacent geometry. Set your light radius to be very small... around 1cm. Make sure your light object is not touching other 3D geometry in the scene.

Olá, Fletch!
Obrigado pela ajuda, mas o problema ainda persiste.
Não havia interseção no objeto de luz e o raio dele
já estava com 0,005m.
Fiz um teste com a mesma cena no MLT e as manchas desapareceram.
O problema ocorreu no Advanced\ Alternative_AA\ 4d. Medium_AA4(ultra).
Acredito que, talvez, o problema seja a escolha do motor de renderização.
Ou existe alguma configuração que evita
as manchas e ainda não descobri.
Hello, Fletch!
Thanks for your help, but the problem still persists.
There wasn't intersection between the light object and
other geometry, and the radius was already 0,005 m.
I did a test with the same scene in the MLT and stains disappeared.
The problem occurred in the Advanced \ Alternative_AA \ 4d. Medium_AA4 (ultra).
I think perhaps the problem is the choice of the rendering engine.
Or is there some setting that prevents
stains and have not figured out.

Re: Como tirar manchas pretas de materiais em vidro?
You will need to edit your preset. Most (or all) of the biased presets (Low, Medium, High) have a maximum ray depth of 5. This means they will go through 5 surfaces. Since your glass is double sided, going through a single glass is 4 surfaces in itself. So it can't penetrate full through a second glass. You will need to find and increase the Max Raytracing Depth value, probably a value like 10 or even 20.
<Parameter Name="Max Ray Tracing Depth" Type="Integer" Value="5"/>
However, with so many surfaces, you are probably better off using the Interior / Interior + render setting.

It looks like the light object is placed behind a surface in the light fixture. It looks like you may have a glass lens on the light fixture, and have placed your light inside of that... I would delete that surface, or change the material for it to be glass>Architectural>common at the very least. I've seen these artifacts many times, and it's always from the light intersecting geometry.

Muito obrigado Fletch!
Alterei o preset (Max ray tracing depth) conforme
a sua orientação e funcionou corretamente.
Gostei muito dessa solução, pois prefiro renders
biased devido a rapidez de renderização.
Até logo!
Thanks a lot, Fletch!
I changed the preset(Max ray tracing depth)
as your orientation and worked correctly.
I liked very much this solution, because i prefer
biased presets because the speed of rendering.
See you later!
