Twilight see's my floor texture as black why is this?

[Sam design]

I have a floor texture in SU which is jpeg repeat pattern of marble tiles as group flat single sided. When I render TL shows it as jet black, what could be causing this?
Thanks
Sam

You probably have a material on both sides of the floor. Marble on one side and black on the other. When that happens, TWR picks the material that is on the Front Face. If your floor is modeled upside down so the back face is showing up, that would be why you are seeing a different material rendered on it.

Otherwise, please post a screenshot or the scene itself so we can look at it.
