Hi there!
I'm working on some 3D old building reconstruction, and I am facing trouble to represent the façade's stone masonry, which is quite particular. If anyone wants a challenge, here is a good one! If anyone wants more or better resolution pics, do not hesitate to ask. Thanks to whoever might help.  |

Looks like hexagons with a noise displacement. Could you post a tile close-up?

Use the stones noise component as a base. Apply a threshold to it to reduce the values so that the underlying shape of each stone is more apparent. Use this as both a height map and a mask for your diffuse stages.
I'd attach an example but apparently my license key has expired again (Don't mind my comment Bella, I've already reported the issue via the contact page). |

You're not going to be able to create stones that regular in size/shape using FF.
Try using Photoshop's Stained Glass filter on some noise and then click invert. Overlay some basic noise textures and an emboss and you should end up with something like this... 
The only downside is that it won't tile. 
FF really needs to add some more stone varieties. |

I'd dare challenge that statement! 
Done in FF... add some noise distortion, and you're set!  --- Crapadilla says: "Damn you, stupid redundant feature requests!" ;) |

And here is the filter...
That is, if you want hexagonal tiles only. In your photo, there are a few pentagon tiles as well... Hexagonal Grid.ffxml --- Crapadilla says: "Damn you, stupid redundant feature requests!" ;) |

Congrats Crap, that looks nothing like the original texture.

Heres another one that may be closer. It still needs to be tweaked a bit..

True, some imagination and color was missing!
(Color could be a problem if you wanted per-stone-colors as in the original, I'll admit.)  --- Crapadilla says: "Damn you, stupid redundant feature requests!" ;) |

Hi all.
Thanks very much for the feedback. Right now, I guess the most suitable one to be used might uberzev's first post, which is the one that might look better and resemble reality the best. The no seamless problem might be solved by just creating a huge image, and use it in for the hole façade as a one piece texture or something. Could you please specify the parameters you used in photoshop to create the texture? Nevertheless, crapadilla's last one looks pretty interesting as well, to be vectorised and used as a CAD pattern for drafted BW plans. Thanks as well! If anyone still wants to try harder, I uploaded here a collection of pictures from the building. Feel free to give them a look! I'll post some images as soon as I have some 3D stuff to show. |

This photoshop file should give you all you need to to customize a tiled stone wall texture. http://www.megaupload.com/?d=XX5GCS4P Due to the way Photoshop works you'll need to crop the image to 1024x1024 before you use it in your 3d program. Also if you want to overlay a different "roughness" texture you'll need to make sure it starts as a tileable 1024x1024 image before you overlay it. |

Thank you very much Ubervev, you've been great help. I don't know how am I going to solve the no tiling affair with the stone pattern, but I guess I will just make the tiles smaller and try to fit it all into the façade.
Again, thank you. chilled115 is pleased, hehe. |

Actually, it does tile properly now . 
(I made a new base pattern using an Alien Skin filter.) |
