Hi Janusz, I like the surface material, could be realy usefull!
However I have 2 questions,
- How to determine brick height (we always have to use realsize brick+mortar height being 6 cm)
- And could it be possible to use my own (seamless) bump/normal texture, preferably with brick shifted placement?

We can not setup both dimensions because there is ratio for width and height. For example 1:2, 1:3, etc
Changing size of tile you stretch mortar and this is bad, so must be done by ratio.

Yes, but for that I have to make new node. Also must be taken decision how to deal with problem, when you want change square tile to panoramic. It will stretched bump map texture. There will be also complicate how to connect image bomber with your tiles...so generally a lot of problems.

I will try do it with another tile node.

bricks should be real size for realistic render and I always model my wall openings for windows at 6cm intervals (vertical only).
You may think 5cm would be ok too but it just doesn't look right.
And a little mortar distortion wouldn't be that big of a deal, at least not to me.
Bump would be nice but is no big deal if it's to complicated :)
Other thing I noticed is that centre of brick is aligned with XZ-plane, best would be shifted up half a brick?

I think everything what you ask will push this surface to way when Node start be very complicate. It will generate problems. Everything what you ask must be done by special Node Shader which doesnt exist.
It is no difficult to do if we will not use image bomber. But how we can do after that fraction with colors?
Thanks for suggestions!

I agree that it is complex, it has always been for me :(
Learn a lot from your nodes though :)
In our line of work we always have to make sure the brick looks realistic, because we want future clients to have a realistic view of what their house will look like.
I mostly use bricks from one of our suppliers for example from vandersanden http://www.vandersandengroup.be/bricks/nl-be/gevelsteen-steenstrip/viborg-ws (3D Mapping link) or from Wienerberger http://www.wienerberger.be/gevel/kies-uw-gevelsteen http://www.wienerberger.be/textuur-lupo.html
Mostly I crop them to a 9 brick wide and 32 brick high color texture, so I can make standard material and only need to change textures for different brick material. From the main texture I copy a bump, normal and (mortar) alpha texture and in some cases a greyscale image to variate diffuse. In that case I have main color and variation in my color texture and only need to make sure the mortar color is what the client wants.

As a example the textures I normaly use.

But each brick type is different often with very specific variation and bump which is almost impossible to do easy with only nodes.

For very default bricks the basic material will be perfect however.

Correct. It is impossible to create one universal surface. For these examples of course the best way is mapping.

I will try post soon this surface with mapping. For that must be only:
- diffuse map (color)
- bump map (is nonsense use Normal Map...better transform it)
- reflection map (it can be for that bump map)
- fraction map (if exist)

...so not much :)

Maybe you can post one set of this bricks (rescaled down because is commercial) and I will make one surface. If not I will find something in my texture base.

As far as I know these textures are not commercial just samples from manufacturer.
On this page you can download the original textures (nice variantion sample :) ) : http://www.vandersandengroup.be/bricks/nl-be/gevelsteen-steenstrip/barok
Or use direct download link : http://vandersandengroup.cedejen.be/sites/default/files/3d_mappings/vds24.zip

The download sometimes includes some of the mortar colors (but not all possible ones)

The famous Masonry designer :D awesome piece of software only downside is it only uses American manufacturers so bricks are often not european enough for our needs. Recommended though for everone else :)

Here's a set of textures I normally start with :
