Agreed. Still, I have a problem with the vertical 'roughness' of the 
bricks and the horizontal 'roughness' of the mortar. Try to give that 
some turbulence (warp {turbulence <0.01, 0.1, 0.01>} for instance for 
the mortar and warp {turbulence <0.1, 0.01, 0.01>} for the bricks) and 
scale that 'roughness' also up for the bricks. It should not have the 
same apparent size as the mortar.

The vertical roughness of the bricks is very similar to what an actual 

intentionally made like that.

Thanks for the suggestions.  I am using the builtin f_wrinkles and f_bumps for
the roughness, but I have my own way of adding turbulence to those.  I made some
much larger changes to the grout roughness to improve that as well.

The rough wood panels on the sides are to give context for the scene I am
developing.

(The green line is an axis I use in my test scenes so I can see where noise
extends beyond the basic shape.)

Sorry, somehow I didn't get the image attached...

I had not been aware of that. In this "bricks country", they are not 
very common apparently, or at least I have never seen them. ;-)

Much better indeed. Personally, I would like to see some more randomness 
in those brick's patterns but that is just my own feeling.

Not common here, but I've seen several houses and other buildings that 

loss some popularity lately.

I like this particular render of the bricks, since I know exactly what type of
brick you are making.   The later render with all of the turbulence wrecks that.

The nice thing is that with about 2 lines of code changes I can have either
version.

I am also thinking about other ways of varying the depth of the bricks.  I am
currently using a moderately scaled f_snoise3d function to push the bricks out
and in from the intended plane of the wall.  It gives interesting effects where
bricks get pushed out at angles.  But there are other ways using warp repeat
patters where I could get the bricks to push out or in as a whole, allowing some
more interesting patterns of brick layout.

I have no clue why, but with LightSys I find I always have to crank up 
the lumens in order to get nice looking results. Otherwise, 90% of the 
time the colors are super washed out. Maybe the default behavior is 
realistic, but it doesn't look nice. To me it looks "wrong".
