Rendering problem
Sometimes I have strange rendering problems.
So does anyone know why it's like that?

Re: Rendering problem
Well, I have not seen exactly that before, though I have seen the black-pixel phenomenon before for various reasons. (Actually I don't think that those pixels are black. Rather they don't have colour at all.)
Have you been able to narrow down any possibilites of what it could be related to?
(Of course you could post a file with that problem here, with your rendering settings and somebody could try to find the problem.)

Re: Rendering problem
It happens when can't save any changes in my model. I deleted few parts and it doesn't show that, but it happened not for the first time.
And yes, you are right black doesn't have color, because in the rendering windows it shows white. All I did was joining objects, with option to retain texture. Those objects
were two mirrors with layered texture. And before trying to save the scene I rendered the image and the mirrors were not rendered.

Re: Rendering problem
OK .. You managed to update your reply while I was writing mine... 
So... Your method provides three possible suspects to the problem:
* It is possible that during the process of joinig to objects you somehow managed to create zero-size surfaces (or at least ver small ones) those can cause unrecoverable problems. (Eg. if a PolyMesh has a surface, that is defined by only two points, then you are in trouble. The editor can not create a surface like that, but those can appear if you import/translate other objects into PME:s)
* I'm not sure how well layered textures respod to the joining process. Have you tried to join with minimal attention to textures first and applying the more complex textures afterwards?
* Surface normals of the mirrored halve could play a part in this. Sometimes you see models that appear a kind of "inside out" while editing them. That is a sure sign.
BTW more complex objects are often better, when they are not joined into one mesh. There are other ways to have the sub-parts follow the master.
That's what came to my mind...

Re: Rendering problem
Hi Nokaia!
The black pixels are most likely the result of an error ("exception") being raised somewhere in the rendering process.
There are a few ways to find the error message:
1. Run AOI from within a command shell (DOS shell, or Terminal shell, etc). There are threads and comments here, on SF, and in the Wiki on how to do that, so I won't repeat them here.
2. Ensure the LogPlugin is installed, and either post the log file, or the "Alert" information.
Without some clear definition of the exception, we can only guess at the cause.
We can certainly suggest things to try, and you can post back saying if that helped or not, but it is always much quicker if you can post the detailed error message(s).
Cheers!
Nik

Re: Rendering problem
This is the source file. Just two mirrors in the scene. Try join objects script with retain texture. Then
render it. Well when you try to join with texture retain this file won't save properly.

Re: Rendering problem
Sadly, the file is now not available.
I know it's been a while, but I have been travelling for work, and pretty flat out.
If Nokiai would like to post the file again, I'd like to have a look at it.
Cheers!

Re: Rendering problem
I think it was just somekind of limit. I wanted to join objects and also retain their textures. Normally this script makes a layered texture, but both of my objects already had layered textures.
