My word Bogie, you must have quite a library of textures and materials. It must take forever to create or find all that.
Have you ever tried Genetica Studio? I think there's also some free version too. I used to use that when I was doing 3d stock models.
Just from doing that I can appreciate all the textures involved in this.
I don't think I would have the patience to put in all those little details, all the stuff on the tables. I love that section at the bottom left with all the tools and veggies.
