This is a tile (cobblestones) that I'm trying to randomly rotate so not to have this cloned pattern. Anyone remember the math function to do this? Aside from tile node, that is.

I don't remember the math function, but know where to find one ;-) http://www.runtimedna.com/messages.ez?Form.ShowMessage=118372 Don't know if that's what you're looking for, but it should do the job :)

msg24 7, That's it exactly. As far as I can tell. I had 2 imagemaps with one mirrored in tile. This blender should fit nicely. Thanks

You can also plug a gentle fbm into the u & v scales of whatever is creating the tiles.

Now that was very usefull, im glad someone asked that question.... Bookmark

is there a way to create the Rain drop effect shown in the link in post 3 using just nodes?

shedo, I believe that sample is node only. It's free too. Just cannot find it. Perhaps you can start a new thread with a cut and paste of that image. Thanks face_off. I'm trying it.

Thanks Richardson, i will do that... And thanx for the Post it has helped me no end...

Thanks for the cool request. Not as simple as the blender method but its closer to what you asked for. I flipped the image, instead of rotating it, but for brick, I think that makes sense. I hope this appears random enough, if not change the argument in 16 to Pow, and or fiddle with value 2 on the Mods.

LOL gmadone, thanks for that. This obviously produces a random effect. Texture coordinates are a straight u/v function? This is paint by numbers. Great! I thought face_off had a new "handle" with the "Real Tile Shader"

Here's one with fBm. Scale went larger and I added more displacement. I think the best thing to do is clone out the one white stone first.

Richardson - extremely convincing. What about an fbm over the top (ie - not tiled) - to add dirt/color variations.

fBm...see what you mean. What a powerful node. I had it connected wrong and still do. Guess it should go straight into reflect or...bump?

From the node system you used in #12, add a color_maths node. Then in value_1, plug whatever is plugged into the diffuse. In value_2, plug an fbm in. Then plug that new color_maths into the diffuse channel. That should break up the overall look of the bricks some more.
