Texture format:

The materials use the new Principled Shader. Modeled in Blender 2.79, cycles render. The textures are .png format which Blender can read if you need them in a different format please contact me and I will send you the required format :)

How to use:

To check out the model open the .blend file and have a play.

To use the model/s in your scene go to File, then down to Append (don't use Link!), navigate to where you stored the Table project and open Object, select the table/stools and then Append from file and voila!
The material and everything should now be in your scene.

Customization:
The basic colour of the table/chairs is changeable - go to your Materials tab and under Surface you will find first the Base Colour, expand this tab and you will see a set of sliders for Hue, Saturation and Value.  

Have a play with these, Hue controls the actual colour, Saturation controls the intensity of the colour and Value the lightness/darkness of the colour.

To get back to the original colour of the texture map, set the Hue slider to 0.5 and the others back to 1.

Note: Changing the original colours this way will effect the colour of the rust - not much or badly, but extreme changes in colour might make the rust look more like chipped paint than actual rust, still in keeping with the model's style - but a good thing to know in advance.

Poly Count/Detail:
The base model is quite low poly, however I have left the Subdivision Surface Modifier on BUT not applied. This allows you to adjust the model as needed.
