Hi Everybody !
i've just finished a urban scene and was starting to batch render a camera move when i realized that the textures had noise.

What can it be ? Bump ? Texture with filters turned off ? (with filters the texture become too smooth and looses the sharpness)
Global Ilumination ?

Another thing that happend was the displacement of the street that dissapeared in some parts of the image after some frames rendered. It seems to be a bug on memory processing of Maya...

here is the link of the movie

Sorry for my english.
Hope you understand.
