While polypainting, I’d like to smear color (like in photoshop) while polypainting. I know I can shift blur, but thats not the same.
Whats the trick to doing this?
You could use Projection Master to drop to the canvas, then use the 2.5D brushes
From searching here it looks like there used to be a smear brush… or is that only in 2.5d? Hmm… never used projection master yet. guess I’ll check the videos on it.
EDIT: ok, got it. Use projection master to drop down to 2.5d, and then select the smear brush. 
Then pick back up in projection master to 3d.
sorry, I was wrong and cant delete my post.
Too bad there isn’t a way to use the 2.5d paint brushes in 3d polypainting.
You can use all of the 2.5D brushes in Projection Master, and now that you mention it, Richard Marklew already pointed that out.
you can also you can use everything in Paint Stop in the same way so all the brushes and tools there are available as well.
Projection master though it a temporary 2.5d, before you lift it back up.
I’ve yet to dig into paintstop though…
Yep they both are but PaintStop is like a nice paint program, its very cool and uses Projection Master.
Both are very very nice tools, but if you are not used to 2.5D they can be a bit tricky at first.
2.5D is given far less credit as a tool then it should have (I think anyway), and most people simply ignore it, its one of the most amazing things in ZBrush.
An interesting way of looking at ZBrush is this:
If you can get it onto the canvas you can use it as a brush, that goes for EVERYTHING. It works the other way too.
Unless I am mistaken 2.5D is why 3d objects in ZBrush are called tools, I might be wrong about that but it keeps me from being driven nuts.
(enter short drive comments below)
If its as easy to drop to canvas, paint, and then pick it back up to 3d again, I’ll have to look into it.
There’s just SO many features to learn! (But I’d rather have more than less!)
It is almost that easy, with Projection Master there are a few options to twiddle about but yes, that is basically it.
I would suggest turning off perspective, and not going out to the edges of your model at first till you get the hang of what its doing, when you make something flat, paint on it, and then make it round again things on the edges can go funky on you. Sometimes that looks seriously cool!
Good to know so I can avoid those issues.
I just moved some uv mapping around, so I’m realigning up textures and displacement maps before I can play with this.
GRIN!
I need to learn about UV’s, all I have done so far with them is make a huge unfixable mess out of a few objects.
UV mapping isn’t that hard at all… as a matter of fact its a less problematic chore than a lot of other things.
I had two items both uv mapped though, and combined the uv maps of both so they could share the same texture and displacement maps. And of course when you move anything, you have to move the already created color and displacement maps, a real pain in the rump.
