View Full Version : Scattering in CS2?
JuddWack 05-29-2007, 10:14 PM I know there must be away to do what I think should be a relativly simple task. Anyway I'm painting a ground texture and have sampled some cigerette butts from another image the ground texture and would like to scatter it throughout the canvas. How would I go about this?

Select what you want to scatter, edit - > Define Brush Preset, give it a name and click ok, then go to brush pallette (f5), find the brush you made in the list, check "Scattering" and drag the bar to a % you like (say, 200% to start). If you want it scattered along both axis then check that box. Drag the slider for "Count" to however many of your samples you want to be spread with each step of your stroke, and adjust the jitter to suit your taste for randomness. You can also go to "Shape Dynamics" and adjust the angle jitter if you want them to be randomly rotated, and the roundness jitter to skew the sample randomly. You can also adjust the input for each kind of jitter, if you set control to off then it will just use the %s in the slider, you can set it to pen pressure etc if you prefer to use that (But it wont exceed your maximum jitter value etc). If you have two samples you can also enable dual brush to paint them both at once.

Thanks man but that doesn't really work for this situation and many others that I've encountered, although I do use that feature all the time.
What you're recomending only defines the shape of the brush and the color that it stamps on the canvas. I want to take an image of a cigerette but and scatter that. Sort of like the way scatter works in 3D max if you are familiar.
As I said, adjust the "count" slider, and the shape dynamics scatter and you will achieve a similar effect by just brushing around. You could also set up a fill but it would look like crap. The method I described in my last post is the best way to achieve this (And requires minimal effort)
you need Painter's Image Hose to do what you're asking - there's no way of doing it in Photoshop.

Maybe you can scatter this "cigarette" image in 3dMax and then render as a jpg file...
Troublesome if u do this!!

huangjmm, I actually have done the 3d studio max thing before if it wasn't to tedious to do it by hand in photoshop. Anyway what I ended up doing is just starting with one, copyin paste rotate merge. Then you got 2, repeat. Eventually it fills up and I just paint a mask to mask out the ones I don't need. I'm really suprised you can't do this in photoshop. That sucks. I run into this situation a lot, seems like it would be useful.

No, no image hose or particle effect in photoshop. I do believe there are plug-ins for this as well but of course you have to pay for them.If you have AfterEffects - you could use that to create what you need, but then that is more expensive than the plug-in solution.
Here is a plug-in I found just doing a Google search:
