Hey, this is awesome! Does anybody know if (and how) it is possible to tell photoshop to use random brush tip shapes for stroking a path? The only thing I know is how to create a random brush through scale, rotate etc - but I don't know how to pick a completely different brush shape...
I don't know about photoshop, sorry. Everyone says the brush engine is much better, so I assume it will do this, somehow.Originally Posted by terraficta

Matthias, I'm not sure if PS can do that (but I'm still at CS1). Painter's Image Hose rocks at this sort of application, though.

I found a photoshop plug-in here but I think you have to pay for it.As far as I understand though, the image hose is a little different to RobA's method, which is common in vector apps (although it looks like GIMP supports it too).
This is a 'chain line' in which you define symbols that fall along a vector line you draw. You can have as many or few symbols as you want and have the ability to alter their spacing, size etc all at once (i.e. each vector line holds the properties to how the symbols behave). It's a bit like the smart symbol tool on City Designer 2 when you want to build instant streets.

After reading the "zillions of buildings" question, and Torstan's tutorial on using the mosaic filter to make a city, I did a bit of playing.
Starting with a road template made by running the mosaic filter with successively smaller tiles and spacing:
I then selected the black, shrunk the selection by 5 px, turned it into a path then stroked the path with the building brush.
I used a number of copies of that (bumpmap, motion blured shadow, outline, colour noise) to make the buildings.
I used a number of copies of the actual template to make the road and colouring.
I drew a quick wall around it all.
Lastly I made it sit on a hill
This is just intended to demonstrate the technique of stroking a mosaic with a building brush. It would work best for a certain type of neighborhood (see earlier in this thread for a discussion)
Sorry to bump my own post, but I wanted to bring this up to the new people here..

Bump away - I'd forgotten about this.
On a related note - I can't get this brush to work with your random density map script. I can get other dynamic brushes to work, but not this one - don't kow quite why this should be?
I think cause it is saved with angular mapping... i.e. it paints based on the angle of the stroke.
The random density script is just drawing points, so no direction.... (that is my guess).
You could open it up and re-save it with only one rank, completely random... then it would randomly use one of the four shapes and some random angle.
