Dynamic Vertex Groups

Recently I have been working to improve Dynamic Paint functionality and allow painless Ptex (Per-Face Texture Mapping) integration in the future.
This next step is _vertex painting_. Basically you'll be able to select canvas output type. Available options will be vertex, Ptex and image output (current dp). Vertex output allows you to paint vertex colors, vertex groups and displaces.
Operating on vertex level makes things easier in many ways. First of all you don't have to unwrap any UV data or load image sequence textures to make it work. It's just clicking bake and seeing the results. Even displace will happen directly by the Dynamic Paint modifier.
Negative things compared to image textures are limited resolution and rendering options. That's why vertex stuff isn't going to replace current Dynamic Paint but to be an alternative way. Hopefully Ptex will be the ultimate Dynamic Paint solution. :)
I made a small demo of vertex group/weight painting. A grass worm.
In that video grass particle length is defined by a Dynamic Paint generated vertex group.
Please note that this is still in very early stage of development. You shouldn't expect any kind of test versions for several weeks.

Yeah, but afaik you have to animate them manually using keyframes?

I'm really looking forward to use Ptex for game development. I do agree it might put a strain on the video card's memory on some cases (because you would pretty much not reuse texture space in efficient ways), but I think this could come in handy for terrain/environment, because I would jut model terrain and then stamp different textures on it and make it look good very fast.
Keep up the good work!

I'm not actually implementing Ptex support. I'm just making sure Dynamic Paint is able to process Ptex stuff when it finally gets implemented. :p
