Back
we just had a similar problem with some wooden boards that we needed the
camera real close up to...in our case tho the problem was jittering in the
woodentexture, now i never fixed the problems, neither did our support or
the guys at alias:/(only lessend it, at the expense of a 5-10 times longer
rendertime), a bug was logged and a suggestion to have mayas filetex. filter
implemented in mr too. Seems theres just problems with the current
implementation of mrfm...sorry for the mood killer, hope you fix it tho, or
can render out those objects in maya perhaps (where also our woodenboards
rendered perfectly!.
