    Vertex Painter 2 is now released!

    http://reissgrant.com/VertexPainter2.html

    Vertex Painter has been updated to version 2.0

    Updates include:

    1.) Paint by texture (Paint by color is still available in advanced roll-out)
    2.) New Mobile shaders allow 4 texture blend and two bump map blend (OpenGL ES2 compatible only)
    3.) Hide the mesh wireframe while painting
    4.) Performance increased.

    You can now paint by texture instead of painting a color and wondering what texture that goes with.

    Purchase includes all future updates.
    Future updates will include dx11 shaders as well

    How do you select the two textures to use?

    Can you tell me what errors you received?

    I'd like to get it working for the 2.6 folks too.

    IIRC it gave an error about float3 should be float4?

    oh and
    Assets/Editor/vertexPainter.cs(205,70): error CS0246: The type or namespace name `var' could not be found. Are you missing a using directive or an assembly reference?

    and
    Assets/Editor/vertexPainter.cs(43,31): warning CS0219: The variable `myWindow' is assigned but its value is never used

    and
    Cg in program 'vert': error C0000: syntax error, unexpected ';', expecting ',' or ')' at token ";" at line 19

    For this, you need the shader package linked in the first post.

    changing the var to int made the script work for me in unity 2.6.1!
    But I cant get the shader to work properly :(
    I get these errors:

    Awesome! nice one! I would have done it myself but have my head in Jessy's shader tutorials over on youtube, so my brain is all mushy and spongy from overuse lol.

    There is now a 2.6 version attached above.

    I'll rewrite the blend shader to be compatible with 2.6, right now it's written with version 3 surface shader syntax so you will definitely get errors.

    Very cool if it works like it should. Wish I could try it in Unity 3. One of the things I liked about making levels in max was how easy it was to do vertex painting with blend shaders in realtime. Look forward to trying this tool out someday in the future :)

    THis looks fantastic. Now we can paint as if it was a terrain like objet. When I'm more advanced in my project I'll give it a try. Will be nice for a beach for instance, to blend the sand nearby the coast and the rest.

    I wish I had Unity 3 beta, I would love to try it out!
    It would be so cool if you got this working in 2.6 or you could make some more demo's so we can drool until the release of Unity3!
    Anyway, this is a tool I've been wanting to see in unity and it is awesome you made this and shared it with the community!
    Keep up the good work!

    The vertex painter works with 2.6, I uploaded a new version today.
    The blend shader will be converted to Unity 2.6 shortly.

    And thanks ;)

    Ok Blend Shader has been converted to 2.6.

    Textures included:
    click here to download 2.6 blend shader!

    blend shader for version 3 beta is on the front page

    Remember, red vertex means texture 1,
    black vertex means texture2.

    Have fun!

    I really want to use this, but am concerned about how it would work with my shaders.

    I'm not very knowledgeable on shaders at all, but what I would love to do would be to make this work with any shader I like, by that I mean the blending of textures using the vertexes and such.

    Ok I'm doing horribly at wording this post well, lol. All I know is how useful this utility would be.

    It will not alter your shader at all. It will change the color of the vertex only. If you are using any kind of shader that is using a vertex color input, then you can see the change in realtime in the editor. That's ultimately what it is for. That's why I included a blend shader so you can see how it affects a model in realtime. A vertex color shader *is* applied when you press "see vertex colors" but then is removed when you uncheck it, and you're original shader will be re-applied. At worse, you may just have to re-apply your shader, but it will in no way modify your shader, just the vertex colors of your mesh :).

    Yeah, that's not what I mean though. I WANT it to effect my shaders, I really really do, lol. I want to be able to use this and edit my shaders so they can recognize the changes to the vertex colors or blend between two textures. Just no idea yet how to do it, and since I can't even get a relief shader (the ones on the wiki, not the bundled parallax ones) to work properly with my lightmapped shaders, I don't see me learning anytime soon, lol.

    I'm not having much luck getting this working.

    win7 version 2.6
    vertex color shader not working, vertex painting opening up, but not painting
    I don't know if the blend shader is working, but the diffuse and normal map for the main color work.

    Apply random colors to ensure the vertices have color, because when you first apply the vertex color shader, the colors are white to start off so it will look like nothing is happening.

    To paint, select a color with the color picker and Press and hold "CTRL" while moused over your object. Also, Ensure the strength is sufficient to paint a color.

    BTW this was developed on Windows 7 64bit, 3.0 and 2.6 and tested on both.
    Let me know if the above works for you.

    At this time it will not affect the shader, but maybe in the future? I assure you the new surface shaders in Unity 3 will be much easier to learn, and will allow for you to write your own. I would also suggest trying one of the great shader node systems here in the showcase forum. If you do, look for "vertex color" inputs and start experimenting.

    Okay got it working, the vertex color shader is still broken, and I'm having some issues with the blend shader, the rock normals are showing through too much and the spec is kinda funky.

    What controls the blending? I'd expect a height map of some sort for the base texture 1.

    They are showing through because the vertices are not totally painted. If they are totally painted, there will be no hint of blending. As for the specular, adjust the specular color and "shininess" value.

    The blending is based on the alpha channel of the blend map. Open it in photoshop and look at the Alpha channel, you will see that it looks similar to a height map. This controls where the texture is blended first. Along with the vertex color which determines which texture to paint.

    The vertex color shader works for me in 2.6, can you tell me if you are getting errors? Or is it just not showing up?

    That would all involve buying Unity 3, which I can't do for the foreseeable future. So I miss out on the node methods cause those developing them jumped ship to v3 as soon as they could. :(

    How do I check for errors on shaders?

    The picture I posted is as painted as I can make it, cranked up the intensity and the color as high as I could and it didnt change anything.

    ShaderLab error: Shader 'Custom/VertexColorsOnly': no subshaders can run on this graphics card

    I have a 9800GT, unless that's too dated...


    MissingComponentException: There is no 'Renderer' attached to the "Main Camera" game object, but a script is trying to access it.
    You probably need to add a Renderer to the game object "Main Camera". Or your script needs to check if the component is attached before using it.

    @winningguy, apply random then try to paint. I'll try to find the problem though.

    @hmacyt make sure you are applying full red (1,0,0,0) and full black (0,0,0,0). Also, the camera does not have a renderer so I would not try to paint its vertices ;). I will put a check in there to disable painting while selecting other objects...

    Also, the vertex color shader is as basic as it gets, it will run on most everything. Not sure why you're getting an error?

    Applying random and then paint didn't do anything.

    The blend shader appears to be working though. Pretty nifty.

    maybe the "no subshaders can run on this graphics card" is limiting it to one normal map or something, I should probably figure out that problem first

    Oh, the BLEND shader, yes this is limited to shader model 3 right now. I will write one for shader model 2 without spec maps.

    Not sure if this was referring to me or the other post above.

    The Blend shader appears to be working for me.

    The VertexColorsOnly shader is the one that is acting hokey.

    But maybe you already knew this. If so, pretend I said something more useful instead.

    I checked and its just the diffuse showing through, made sure the vertex colors were as absolute as possible, I'm updating my video drivers just to make sure that's no causing any issues, they should be fine though.

    Ok, package is updated on the front page.
    Vertex color shader is NOW included, somehow got left out of the previous package...

    "Index out of range" error fixed.

    Fixed an error when trying to paint vertex colors on a camera or light. :b

    Please let me know if these changes resolve your issues, or if you have any more issues, or questions.

    Are you using Unity 3 beta or 2.6?

    Ah ok, it appears Unity 3 is compiling the version 2.6 shader before I can package it : /

    Let me fire up good ole' 2.6

    Ok hmacyt, download the separate new vertex colors shader for 2.6 on the front page, overwrite the shader that was included in the package, let me know how it works.

    yay the vertex color is working perfectly, no errors, but the other shader is still having the same issues, figured out its tied to the lighting some how...

    the sand is still transparent and it only shows up with light.

    Regarding the VertexColorsOnly shader... for some reason it's still telling me that it has errors.

    Code (csharp):
    1. Unrecognized renderer for #pragma exclude_renderers: gles
    2. Unrecognized renderer for #pragma exclude_renderers: xbox360

    I'm also getting a message that no subshaders could run on my graphics card. I'm using a Nvidia GeForce GT230.

    Ok, try this:

    set the vertex painter to the settings in the screenshot and press the "click to apply colors to all vertices" button.

    Also, set the colors to light grey and drag the shininess slider all the way to the right

    Take a screenshot with your vertex painter settings and the plane in view so I can see what you have.

    It should look close to this:
