Hopfully this should solve some issues people have with vertex painting in Unity. We're still adding features but it's pretty fast already and we've used it in production for a game where everything is vertex painted.

Sound up on the unity forum if you have any ideas for features

I would be interested in testing this and making suggestions.

Our game is full bright and relies heavily on vertex colors. I don't like any of the existing options and I need to be able to assign vertex colors in engine, not Max due to the way our levels are laid out.

is it works with instances?
( if i copy one object and want to paint different vertex for each object from the same instances)

That's what i would want to do too.

Jesse, sent you a pm

okkun

Yes it should work on instances.

long answer: it stores vertex colors independent of the meshes, duplicating an object will require you to add the new object to the paint group, but otherwise it will retain the original instances

Beck

to give an even longer answer about the instances, the vertex colors are only applied during runtime and while you're editing them, but it's all cleaned up back to the original mesh reference in all other situations. this means you can still modify the original mesh / prefab and the vert colors will remain on the object!

that said, changing the vert count of a mesh will break vert colors on an object currently. in a future update we'll have functionality for storing transfer info so that you can retain vertex colors across a vert-count change. however, you can currently copy vertex colors from one mesh to another using the Radial Blending function.

Just wanted to post another promo image for this, here's the full UI if anyone is interested.

Clean, User-friendly interface

Awesome, just in time! Have had trouble with other Unity vertex painters in the past so I'll definitely check this out.

Forgive my ignorance, but how difficult would it be to use this with custom shaders, like Skyshop, Chickenlord's Shader Bundle, etc.?

Beck

It depends on the specific shaders in question (I don't have experience with either of those packages) but if the shader already supports vertex colors than it should work right out of the box.
If the shader doesn't support vcolors it is relatively simple to include vertex color support. The simplest way is to multiply the vertex colors by the end result of the shader you're modifying. Here's how you do it:

In the Input structure of a surface shader, make sure you have "float4 color : COLOR". Here's an exmaple of an Input structure with vertex colors included:

struct Input {
        float2 uv_MainTex;
[b]        float4 color : COLOR;[/b]
};

Then, to multiply your vertex color by the result, multiply IN.color by the Albedo. Here's an example:

void surf (Input IN, inout SurfaceOutput o) {
        fixed4 tex = tex2D(_MainTex, IN.uv_MainTex);
        o.Albedo = tex.rgb * IN.color;
}

Each shader is different, but this is the general makeup of Unity's surface shaders so in most cases that should be applicable. Hope that helps!

Thanks for the info Beck! Will give it a try when I get time.

Awesome, im going to start using this.

okkun

added some shaders ( you don't need Vpaint to use them )

cool, was it alright to work with? We're still looking to improve it so let us know if you have any questions or requests for features.

We've got an update with some bug fixes and perf improvements but I'm not sure what new features are making it in now.

I'm a bit late to the party, but beside the AO youtube tutorial, are their any plans for future tutorials? I've been playing around with the tool and I know it's capable of doing exactly what I want it to, but I can't quiiite get there. Certain aspects of vPaint are great/intuitive, but others are a little less natural feeling.
