Can I make paint drip waaay down the canvas?
Hi,
I'd like to be able to drag a stroke horizontally (or diagonally) across the canvas and have the paint drip way down. I'd like to do it in watercolor washes and maybe something thicker like oil. Like someone painting very sloppily on a wall.
Is that possible? So far I've only seen how to make water color diffuse. But I'd like some real big drips and going far down the canvas.
Thanks.

You have to create and animate each drip separately.

if you don't want the drips animated you have the option of custom brushes - take a look at (e.g.) Water Edge long for some inspiration.
Re: Can I make paint drip waaay down the canvas?
This is funny.
I posted this in lostmarble by mistake. It was supposed to be a question for Corel Painter.
But it turns out to be useful here, too, since I do want to use both programs together for my project.
I understand how animating the drips would work. And the Water Edge brush is great.
One thing I've noticed is that with that brush and some of the other similar ones with feathered edges, when you blow them up to say 100 or more, you see the feathered edge cut off sharply instead of fading all the way out.
Is there a way to change that?
Thanks.

Apply some blur?

Re: Can I make paint drip waaay down the canvas?
that's a "feature" of the brush design. The water edge brush is a multi-brush with each variant 512px square. You could adapt it or create your own with a smoother fade to 0% opacity at the edge.
Re: Can I make paint drip waaay down the canvas?
Don't think I'd want to blur it. I love the way it looks.
I'll try to adapt or create my own. Haven't looked yet, but I'm assuming there's a tutorial that shows how to do that?
Or, I guess, since they're png files I could just alter that.
Seem right?

Re: Can I make paint drip waaay down the canvas?
if you find a good tutorial on making brushes let me know!
For "tint using stroke colour" I think that 100% black = stroke colour at 100% opacity; 100% white at 100% opacity OR black at 0% opacity = stroke colour at 0% opacity.
Most brushes are in .pngs with square dimensions such as 256*256 px or 512*512px - but I don't think there are any actual constraints (e.g. an oblong brush 5000*2000px works ok).
Align with curve means that the top of the png follows the direction that the path was drawn (i.e. a L-R stroke has the top at the right); which is why you'll find that asymmetric brushes often have a left handed and right handed variant. If the brush is not aligned to curve not the .png is aligned with the render (i.e. the top stays at the top even if the vector layer rotates).
the number of brush instances in the path changes if the line width or segment length changes --- IMO obvious - but if you've animated the path - e.g. bones - the length can easily change and that can give "unexpected" changes in the visual appearance of the stroke. I think (not totally sure here tho') that scale compensation also causes such changes (IOW line width changes as a result of zoom / z shift relative to camera implies different number of brush images) .
If you plan to use angle drift / jitter you might like to consider using a circular "active area" in the .png -- in these cases I keep my brush details in a circle with diameter about 75%-90% of the image width (in a square .png ofc!!) Also helps avoid jaggies hanging off the path as it goes round curvy bends.
Think about wrap round / overlaps -- e.g. if you want a tidy line up in an "align with curve" brush make sure the top of the design lines up with the bottom!
I'm sure there's more but ...
anyway -- hth!

Great info. Thanks.
If I have any success I'll post it here.

Re: Can I make paint drip waaay down the canvas?
So what I've figured out so far is that there are certain tweaks you can make to the strokes. And you can create your own brushes from png files.
But I don't see any way to fully tweak the brushes. So it seems like the only thing to do is create my own png files.
And I'm assuming that if I make the files large the brush in Moho will be able to go as large as that.
Sound right?

Are you talking about an effect somewhat like this?

Yeah.
And if possible, multi colors. But I'll take what I can get. Looks good.

What do you mean by mutli colors? Do you have an example you could show or link to?

Re: Can I make paint drip waaay down the canvas?
What might be fun is use that element as a mask over a rainbow gradient, and then use Smart Mesh to 'liquify' the gradient image (but not the mask) to 'flow' with the animation.NealF wrote: if possible, multi colors. But I'll take what I can get. Looks good.

No masking...just animated the particle drip color.
