Edited material wont show in render

[Dorina]

Hello, I've been having problems while rendering. I have edited all the materials on my model but after rendering they don't appear edited, they don't show reflection or bumped or what else.

The preview on the Material editor table,for all materials looks fine but on the render image no, not edited.

I'll attach 2 images to give a better idea what my problem is.
