Procedural Photoshop Bump

I admit this is soo N00b!. But how can I get that dimpled surfaces?

Max procedures don't capture it. The built ones in photoshop dont seem to give the effect (they overlap or they are different colors).

The last object I attempted this on I spent hours meticulously copying spheres (array wouldn't work since it wouldn't follow the surface) to create a surface in max to export to PS. Never again!

Doing it manually wouldn't take much time. Just paint a white dot on a gray bg in photoshop, duplicate it over, then duplicate those 2, etc. It's exponential so in less than a minute you'll have a screen full of them. That way you can customize the dot exactly how you want with gradients and smooth edges and such and duplicate it.

Then in 3d just set it as a bump or convert to a normal map.

Thats pretty much what I did in Max. It wasn't quick. I tried in pS creating a custom brush that used dots and had them follow paths but I couldn't get the dots to be consistent on the brush path.

The thing is look carefully.. Those dots follow the surface. Now if I need to cheat yea. I can do it your way but "less than a minute" I dont see how for first you copy into new layers for each dot which you then have to combine.

There is no PS plugin (hopefully free) that makes a procedural array of mashed dots?

I haven't used this PS plugin yet but it might be able to help you. Looks awesome.

looks like the balls are random. they dont follow any pattern.

how bout making a shit ton of really low poly spheres in your 3d program, and use physics to drop them in between 2 planes so they randomly stack up like marbles or w/e. then bake that onto a flat plane.

if you need them to follow the black lines just do it in zbrush. loads of tedious manual work, but it's probably faster than anything else. you should be able to mirror it in all 3 axis, which makes it probably not all that tedious after all.

An example with a bit of Googling

You might try making a quad sphere (so no pinching at the poles) and tiling a small hand-made map across it. I don't think anyone's going to complain about bumps not lining up perfectly with the black grooves.
