Blender: Dynamic Paint Basics

Creation date: 2010-8-4
Last update: 2011-8-26


Dynamic Paint is a new Blender tool available in versions 2.61 and later. It allows you to use meshes and particles as "brushes" to paint on other objects.

This tutorial shows step-by-step how to set up a simple scene using Dynamic Paint. For a more detailed guide, that explains purpose of all those settings, check my Dynamic Paint Guide.

Check out my blog for more info about Dynamic Paint.

Tutorial contents

1. Initial Setup
2. Canvas
3. Brush
4. Baking
5. Rendering
6. Examples

1. Initial Setup

For this tutorial I have prepared a simple initial scene to begin from.

Get the Flash Player to see this video.

Download the initial *.blend save.

It has an animated sphere to become a Dynamic Paint brush, and a subdivided Suzanne monkey head to become a canvas.

2. Canvas

First I'm going to set the monkey head to a Dynamic Paint canvas. That makes it receive color from brush objects.

 Canvas Object

Enable Dynamic Paint Canvas

First select the suzanne object. Then go to the "Physics" tab from top of the properties window.

 Physics Tab

Now click "Dynamic Paint". A new "Dynamic Paint" panel will appear below. While "Canvas" selected, click "Add Canvas". This will enable canvas properties for current object.

 Enable Dynamic Paint  Add Canvas Type

Default canvas settings are fine for this tutorial. I will adjust them further in "Baking" section of this tutorial.

3. Brush

Now setup the "Brush" object. In this tutorial it's the sphere.

Select it and add "Dynamic Paint" modifier from "Physics" tab just like before. This time select "Brush" and click "Add Brush"

 Paint Object

Now brush settings are visible. For this tutorial you only have to change brush color.

 Paint Settings.

Click the color selection box and change color to blue. That's all for brush settings.

4. Baking

Now that both brush and canvas have been set you are ready to try it out.

Dynamic Paint is processed real-time as you playback the animation. Click the play icon on the blender timeline or press "Alt + A". You should see blue paint appearing on Suzanne as the sphere touches it.

 Timeline  Suzanne painted

You can also bake canvas, so that current "paint animation" gets saved. To do that, select canvas object and scroll down Dynamic Paint settings until you reach "Dynamic Paint: Cache" panel. Open it and click "Bake".

 Bake

5. Rendering

To render the result you have to setup a new material that uses vertex colors generated by Dynamic Paint.

Select canvas object and scroll down to "Dynamic Paint: Output" panel. Now click the "+" icon next to "dp_paintmap" box. This will add a new vertex color layer to output canvas results to.

 Add new output layer

Now you have to add a new material that uses those vertex colors.

While canvas object selected, select "Material" tab and add a new material if required.

 Material Tab  Add new material

Now scroll down to material "Options" and select "Vertex Color Paint". This will make material to use vertex colors.

 Enable vertex color rendering

If you render now, you should see paint on canvas mesh. You can also change brush object material to blue. Here is the final render:

Download the finished *.blend save.

WOW this works exelent!!! great feature!

mini tut based on the info in this page =°.^=
http://www.vimeo.com/13950684

by the way, could it the system or scrip used to bake the image secunce be adapted to bake normal maps??
(once the bake system, fully works with multires, ofcourse)?

thanks

I am new to blender, but thanks to tutorials like yours, i am quickly learning just how powerful an animation tool it is. My goals are to build a game, (of course), but of all the 3d softwares available, Blender seems to be the easiest to learn. and because of Python support, my programming language is chosen for me, no annoying additional skills to learn like with openGL.

This paint build, although the build differs slightly from 2.49, the paint function should allow me to build the pieces, the objects needed to piece together the whole. thanks for the impressive work you've done.

Wow, this is impressive. I have three recommendations. One, add a way to do alpha for the paint maps, there is a special color wheel in the themes section that might do what I'm talking about. Two, a small tutorial on how to use displacements maps, I use the displacement modifier myself. Lastly, something about what wetmaps are and how to use them.

This is really amazing. Keep up the good work.

Could the mesh paint modifier be optionally made to generate and update dynamically a vertex group of canvas vertices inside the paint mesh? Oh, please, please, Tell me this is possible!

Just dinamically painted wet my pants after testing this.
It SHOULD be on trunk now, you can´t really imagine how impressed I am, now gone to get some dinamic paint towel to clean this dinamic mess :D.

Very cool stuff.
Would you mind updating tutorial?
I can't seem to get it to work with particles nor can I get the displacements and wetnaps to work.

Your "Just A Cool Paint Test" would make the perfect tutorial. It seems to cover most the process involved.

Thanks,

An important feature, I'd like to try. So far, I haven't been able to make this work. Can you please post a minimum .blend file as an example?

Until a better demo blend is available, this bare bones file correctly demonstrates the basic feature for me.

The tool is great.

With the tutorial though, I found a little problem, which is that it doesn't say that the baking outputs an image sequence that has to be mapped to the UVs or that it is usually located in C:\tmp\ . It took me a while to figure out.

I am using the latest build for Mac 64 bit from graphical.org. (Blender 2.55 [33134] w/ Dynamic Paint, OpenMP & Collada (64Bit) ). When I try to bake the paint it will not save the sequence. Has anyone had any luck running on the Mac?

Anyway Dynamic Paint looks like a terrific addition for Blender from the videos. Thanks for the all your efforts.

Hello, MiikaH, I hope you can help me.
I follow this guide, but whem I press "Bake Dynamic Paint" button, I receive "Bake cancelled" message, and nothing happens.
My system is Ubuntu 10.10, 32bit. I tryed different builds from graphicall.org, but every time I face the same problem.
Also I tryed to change DynamicPaint options, to patch official source, to find discussion of such problem by "google", nothing could help me.
DynamicPaint is a great tool, but I can't use it. Hope you will tell me what to do.

@snovvfall

That sounds strange. Cancellation should happen only when ESC is pressed.

Can you run Blender from command line and check if there is any console output? Also make sure you only have canvas object selected when baking.
snovvfall
Feb-06-2011 15:22
console output is "Baking cancelled", no any more information. Canvas object is selected, paint object is added and animated, unwrap done. ESC button is ok and not pressed. I may show screenshots if needed. Thanks.

I couldn't find the reason, but it seems to me, that I solved my problem. I'm writing to people who have it too: if you use DynamicalPaint and receive "Baking Cancelled!" message, you may use this build http://www.graphicall.org/builds/builds/showbuild.php?action=show&id=1703 (for Ubuntu 10.10 x86 32bit). It will require some libraries, but it is not difficult to install or to make links.
I'm sorry for disturbing you, MiikaH. Your DynamicPaint and other projects are great tools, and I hope we will see them in official version soon!

@snovvfall

Glad to hear you solved it!

Unfortunately I'm still not sure if it was the build or my code that caused this. :x I checked it up yesterday and couldn't find any real reason for that to happen. Perhaps it was a bug I have accidentally fixed in the latest Dynamic Paint version. :p

When you say you need to open "paint0001.png" as an image sequence, the option to do it as a sequence doesn't appear and the file does'nt seem to exist. Is there anything wrong in what I did? Or is it my version of blender?(I downloaded from this site for the dynamic paint)

At the 'Render' section, I go to open up a file, but I dont' see options in the panel for 'sequence' or 'file', it just opens up to the baked cache, and there is no .png there, just .bphys files. Am I missing something? Thanks

Oh and sorry, again, but this turorial is soooo old, it really needs to be updated... Ive got the same problem with everyone else, the paint0001.png or whatever problem....cant seem to actually find the image

I downloaded Blender 2.58.1 r3097 on Windows Vista 64 bit Blender GSoC Carrot Branch (32-bit + 64-bit). I followed your tutorial but when I go to the physics tab I could not see the Dynamic Paint tab. Kindly help.

Fantastic,I downloaded Soc-20110-Carrot and it worked, may thanks. I have been trying to do the dynamic paint + indirect light but could not. Do you have a tutorial for that. I am willing to pay for one.

Hi Miika, and thanks for all these explanations, I'm having some problems when rendering. For some reason, after baking and all, th epaint won't show up on my model. I have aplied a toon shader to it, but I doubt that is the cause.

Hi, thanks for this great tutorial!
Maybe you forgot to add that the canvas obj needs a few multires levels for it to render/appear ;)

IS this Blender Render or Cycles They are very different for Dynamic Paint.
thx
Aug-04-2017 00:09
can you add the dynamic paint effect options to weight mode.
or can dynamic paint paint create verext groups just like weight option.

that would be awesome.
