    Looking for a procedural texture...

    Hi,

    I'm working on a project where I need a procedural texture I can use to displace an object. (The finished object will be exported as an .stl) The texture I need has to resemble the dots/grip on an American football. I've been playing around with the crust texture, and it's not terrible, but it still has too many flat areas with no dots, and the dots overlap too much, meaning they bleed into each other too much. (attached pic shows my attempt so far, and what I'm trying to match)

    I've tried the veins, and honeycomb textures, but they are too sharp.


    I need to have this completed in the next day or two, and have zero budget for it...

    Any suggestions?

    Cheers,

    Derek

    Have you tried RMan Collect (from Denis Pontonnier) > (3D) Cells texture, using mode F1 Smooth-Step or maybe Cosine ?

    Thanks for the suggestion omichon...

    I've had a play with it, and it's certainly an improvement, but I'm still left with bare patches where there aren't any bumps.

    I might be able to get by with this, but if there's any other options, I'd still like to hear them.

    Not the procedural I am talking about.
    You have to install RMan Collection from DPont, here.

    It's not strictly procedural, but I created this simple displacement texture in Photoshop using stacks of inverted Stained Glass texture from the Filter Gallery.

    I built my football so that it was standing point down on the Y axis.

    Then I set the texture up as a surface displacement using Spherical on the Y (although you could also try doing a proper UV map, which would probably work better).

    Fairly pleased with the results.

    Here are the basic settings on the ball, for what they're worth.

    I donīt think that is a good choice, the cell texture isnīt uniform, unless you reduce the jitter..but as soon you turn that down completely..you will loos the main dent shape.

    Bump array perhaps, you can also use previous layer gradients to control it.
