List,
I'm modeling a highly detailed F1 race car in Rhino 1.1 and exporting as a
Moray udo object. I think I have encountered some limits in file size
because of the following:
If I export the entire model as a udo and attempt to render in Moray
3.2/Povray 3.1, I will get an error like this:
error: no triangles in triangle mesh
rear_susp_object62
I was able to locate 'object62. Knowing what the object is I went back into
Rhino and exported a smaller portion of the model which included 'object62.
This time I was able to get a render with Moray/Povray. This leads me to
believe that I may have run into some kind of limitation for the size of the
file. Would this be the case? Workarounds?
Thanks, in advance,
Steve Clarke

What that error message usually means is that your mesh object(s) contained
nothing but degenerate triangles which POV-Ray will not accept. I have
seen this in the past when using 3DWin to convert between various formats
but only rarely.

The main clue for me is that the same object rendered with no errors when it
was exported in a smaller group of objects. A much smaller file size.
Although I kind of wonder if my system didn't make some errors while
handling the really large export of the entire model. It was swapping out
to disk a lot during the udo translation operation in Rhino.

I have rendered massive meshes before without problem but they were
obviously well behaved and written properly. As I said sometimes
something gets messed up during the translation efforts and you
end up with millions of degenerate triangles that POV-Ray silently
and dutifully removes for you. I am fairly certain that in your
case file size had nothing to do with it.

Thanks,
I'll look at model clean up next.
