    The result with this 2 screen is the first screen with the character, with "blood decal" all the tim at same place
    If you haven't setup the character's UV1 map or physics asset there's no point testing any further, the results will invariably not make sense.

    For setting up UV1:
    1) Go to your favorite DDC - Blender/Maya/max etc.
    2) Create a new UV map for your character in the UV1 channel (instead of the usual UV0)
    3) Unpack all faces onto unique UV islands. You can do it any way you like, the only golden rule is that each vertex/face needs to occupy a unique spot on the UV Map. i.e. No overlapping faces, so just like a Lightmap UV.
    4) Export your character back into UE4 again, now the "Don Mesh Paint UV1" node will work because it has the right UV data to work with

    For setting up physics asset: Follow Epic documentation on physics asset creation/etc.

    The precision of your Hit Result determines the precision of your paint decal placement, so you need a physics asset that very accurate; it should envelop your character as tightly as possible to provide good results.

    You can open the demo character's UV1 map (in Persona -> Show) and its physics asset to see how both are setup.

    Thank you for you quick support!

    "Skeletal meshes: A lightmap UV is compulsory for skeletal meshes in this workflow. So in addition to your regular UV map (UV0), you will need to create a simple lightmap UV on UV1. You will need to ensure that every part of your mesh (per-pixel) has a unique coordinate in the lightmap UV you’ve created. Now you should be able to use Don_Mesh_Paint_UV1 to paint without any issues."

    And

    "3) If you have already setup the Physics Asset and the UV1 special UV map for your character (as per the docs), then a screenshot of those will help as well."

    How i can do this? please, thank you

    To preface, have you seen the Quick Start Guide page and the Preparing Your Mesh for Painting steps already? There are certain mandatory setup requirements for skeletal meshes which those pages talk about.

    Assuming you've setup everything up as per those docs, can you share the following:
    1) Screenshot of your material (just the part with the Don Mesh Paint UV1 node is enough)
    2) Screenshot of how you're calling the Paint Stroke node
    3) If you have already setup the Physics Asset and the UV1 special UV map for your character (as per the docs), then a screenshot of those will help as well.

    One useful debug technique is to bring your character into the example project and replace the demo character with yours. That will allow you to focus on verifying just your character's setup first.

    Hi, i but this awesome plugin,
    but I do not know how to set the material for my character, once I'm going to wear the uv1 mesh paint (Don_mesh_paint_uv1), what should I do?

    Error in paint stroke component: "This materias is not configured for layer 0.."

    Can i fix this problem if i use plug-in of 4.20 with Latest UE?
    Major Bugfix - Skeletal Decal Sizes are now consistent

    Thanks to Rita Shinenen 's excellent bug report I was able to diagnose and resolve the longstanding issue of inconsistent decal sizes (on skeletal meshes) which other users like cpenny20 have also mentioned in the past.

    I have sent a hotfix to the former for testing, if all goes well the patch will be formally introduced along with the 4.21 update for the plugin.

    Thanks again to Rita Shinenen!

    Is anyone having luck getting this to work on 4.20.3? I just downloaded the plugin and paint is not working in my project, I also tried the sample project the creator made and it did not work either!

    Thanks.

    EDIT: Nevermind, it just appears that the landscape bounds are shared between projects, so the settings I had for my project invalidated the demo project.
    Thanks for the update. Yes it is shared if you have the plugin installed at engine level (true for marketplace plugins by default).

    You can simply copy the plugin directly into your project folder for maintaining unique bounds per project.

    I have some questions regarding this addon

    1) Is It possible to create a BP_projectile with multiple brush/decals ?
    For example:slash decal , bullet decal , blood and many more....

    2) Is It possible to control the opacity, size of the decal on the character once It's applied?
    For example:regeneration , getting clean.

    3) Do characters require to use Blueprint?
    Sorry for the late reply, been super busy with my game's biggest Steam update

    1) Yes. complete flexibility is offered at the API level. You can extend it to create custom "paint projectiles" as per your needs

    2) The eraser functionality allows you to remove painted areas and restoration of an entire actor/material (purge) is also supported. You can also simply choose to negate the mask's alpha channel in the material for cheap gradual transitions without touching the render target(s) again.

    3) You can use any format you like - Blueprints or C++

    Hope that helps

    This is my material - http://prntscr.com/kveupc

    I can paint landscape with blue or red color. It works fine, but collision works wrong if I repaint some areas.

    For example - I painted some ared in red color and after that I repainted that area with blue color - http://prntscr.com/kvepgt

    But collision still thinks that this is a red color.

    Is it a bug or maybe something is wrng with my material?
