For some reason maya is falling over when rendering, I am using mental ray and global illumination.

The error that is logged in the script editopr is as follows:

- - - - - - - - -

// Error: (Mayatomr.Shader) : TV_TVRSIDE_very_daSG: no shader assigned in material //

- - - - - - - - -

I've tried removing all textures and replacing tem with a basic lambert shader but still get the same error message. Could it be to do with a corrput piece of geometry or an assigned ma\terial? I don't know.. any help would be greatly appreciated,

thanks,
