Indigo Renderer Forum

I know that this bug have been discussed very often, but I still want to request that this Bug has to be "killed".

I made some test to see the Problem with Bidir and here they are.

All Images with Hybrid and Metr.-Settings ON.

PS: If requ. I can load up the .blend-File of the Scene

Hi Sebastian,
what Indigo version are these made with?

They are made with:

indigo_09_test4

Ok.
Can you please make a much simpler testscene?
Preferably something with just one object (or two) that show the bug.

I don't know how I can Simplify this, i thougt the Bug was clear visible,

it's 1st the blend-null Material what still don't works


and second the Glaß-Material which has a stange Color....

Should I mark it ?

Ono already said, if you'd render that null mat forever, it will clear up.
and the Glass (there is no "sz = ß" ) isn't quite obvious to see...
which mat settings for the bulb? does it have thickness (is it closed)?
Is it hollow (is there a smaller "bulb" mesh inside, with IoR 1 and higher percedence?)
what's your raybouncedepth and what're your max num consec rejetions?

isn't bulb made of a blend too ? Using some transparent dirt texture I'd say...

If tha null material still is pitch black after more than 3 hours, it's a bug and not lack of patience!

i think kram was referring to the way that bidir is implemented in indigo, that in theory it will become transparent like its supposed to (the spider webs) if its rendered for infinite time. But that sounds mighty impractical.

Here are the Material-setups:

the lightbulb mat looks fine in the scrennie you gave...

are you sure ? I'm not used with blender but the outer faces looks to be under the inner ones, maybe the normals ARE inverted (that's not obvious to see as bulb is thin), maybe the ones you see going outside are from the inner part...

you should try to make the normals shorter - by a tenth or more...
the normals should be shorter than the bulb's thick

Anyway... the bulb really looks strange...

Mark's suggestion is purely for appearance in the editor, of course, as the length of the normals is irrelevant to indigo. Isn't that right, Mark?

yeah - I added that to CTZn's thoughts...
maybe, they indeed are inverted
