Black Phantoms [.. is killing my renders]
I have some weird black-ish polygons appear my renders.
It's not simple geo.
Because it's not in the scene.
There is no such objects.
It appears only on renders.
It is only on one building (and it's clones)
When i switch off some layer it kind of goess away...
That gives me a hint that problem is with objects in that layer...
So i am in a process of catching this fucker...
But.. Did anyone have this kind of phantom bug?

I'd be more worried about the space invader tetris ribbon taking over your scene.

haha.. i see what you did there ))
Ribbon is a friendly alien. Also it is controlled by the PATH itslef...
But that cunty bug is there. And it is a real one.
Solving this may help others a lot.

Multiple faces occupying the same space?
I would turn on the usual Render Elements and see exactly where the "blackness" is coming from.

Re: cunty bug...maybe flipped or dupe faces, try this :
& always render an ambient occlusion pass first to highlight cunty bug areas.

you can try raising the secondary ray bias in the global vray settings. That's worked for me when I had geometry problems (double faces and what not) that were to much of a pain to fix.

I located the first fucker.
This object positioned in the other part of the scene.. somehow was the reason of the fisrt black phantom.
Now anybody shed some light...
How is it possible?
Some weird black polygon like spot appears on object because of some other object that sits way down.
The only explanation is it is some kind of a shadow??
But that wheel is not above that roof.. Its under it...

Usually you'd turn on:
Those 6 passes are the primary breakdown of the RGB; that plus (as mentioned) an AO pass will give you insight to 99% of problems arising in the buffer.
And normals... thanks Dan.

I'd throw in a normal pass too, check for funky normals.
Looks like you're just going to have to pick at the scene until you find the offending objects.
From the looks of the mesh on that wheel, I'm guessing it was imported from another program? Alot of times you can have problems with the normals on OBJs or other formats.

Not to mention odd additional geometry coming in when you aren't expecting it.

Those areas are so basic I would have deleted them and built again.
Max does have a Mesh Inspector but it doesn't have a UI and only pops up messages if it detects errors in your mesh when "Auto Repair" is disabled.
Docs are wrong tho', they've moved it to the Tools menu in 2015.
I'd much prefer a Modo style Mesh Cleanup UI informing me of any errors and the option to fix:
...but this is AD :/
There's some diagnostic tools buried away inside Automat I use all the time, useful for quickly zoning in on problem areas, I use it mainly for prepping meshes I send to Modo / Meshfusion and Zbrush when I want all quads.
