Hey guys, I made this from my own photo, and I thought it turned out pretty well, so I threw it up for download. Feel free to offer me some feedback.

Here’s a better render, sorry about the first one. It was just a material giveaway, but since it got put in WIP…
one note
can you add the object info random so that when you use instance it
does not repeat the pattern
nice mat
thanks for sharing
happy bl
I did not know about that. Thanks for mentioning, RB.
I did try to minimize the tiling in the diffuse texture.
For Eevee you should add the lightprobe to gice a better render
to give more flexibility you can add some color ramp on input field
and change the color with a mix color node
will see how to add in bl 3.1 the microdisplacement effect
will come back later with a more advance set up
sorry still learning the bl 3.1 new features
happy bl
Yeah, I sort of knew about that, but for the most part I am in the dark about eevee. First thing I do when I open blender is to switch to cycles and crank down the max samples a little.
That and move the lamp to the other side of the cube haha.
If after you crank down the samples and move the lamp, you go to the file menu > defaults > save as startup file, the samples and lamp will automatically be where you want them in the future with new files 
I actually make multiple ‘start’ files, but I usually just open Blender, and go straight for the Y axis slider out of habit. The main one use other than the default has the camera facing straight forward at eye level and an HDRI loaded.
here is a ore advance set up
with color ramp on inputs files
a mix color shader to change concrete color
and for cycles only added microdisplacement
which gives strong but adjustable at any zoom level or camera distance
file is here
i could not include the HDRI mop
file was more then 5 MB
so find one and add it in world nodes set up
haver fun

Weird, I thought I already had a roughness in there. My bad.
what are you smoking LOL ?
happy bl
can you upload the new map or give link so we can add it
thanks
happy bl
is this the roughness map ?
it looks more like a displacement map
see this site on PBR
PBR Maps - Diffuse, Normal, Roughness, Displacement - Prospero Coder
roughness map looks a lot more greyish pale
have fun with PBR
thanks

Try inverting it.
Hi there,
Great work, thanks for sharing. Make sure to check Materialize (if you don’t know it yet). It is a really good free tool to create all kinda PBR maps from photos

Yes, that’s what I used to make the tex. It’s why the roughness map is inverted, because it puts out a ‘smoothness’ map instead which is the reverse of a roughness map apparently. Great app. I have used other programs previously and I tend to prefer this one.
see CGcookie intro on PBR maps
very interesting

there are also tut videos from Jayanma short and nicely done
