Vertex Painting in UDK

video player

In this demonstration, Tor Frick shows how to use vertex painting in UDK. 

He shows the techniques needed to create a vertex paint shader that blends between plain and painted wood, along with adding rust to a metal material and using a material instance to efficiently reuse the first shader for both materials.

nice tutorial. I am wondering if I could vertex paint in UDk and than export it to 3DSmax and THAN import it into the CryEngine 3 ? or is there another way to vertex paint like this ?

so do vertex paiting in cryEngine.

Exactly what I've been looking for.  You go straight to the point.

Straight to the point, and a much needed, intro-level tutorial to how blend shaders work in UDK! Thanks for this, was having trouble setting one up until a friend linked me here. Smiling

Thanks so much. This will really help with mixing up my modular pieces. Cannot wait to show to class mates as well.

you know those red dots that you can paint on? well i dont get them am i able to get the red dots on the static meshes?

How did you make the custom blend mask texture?

I've followed each step in this video and it doesn't work. There are no changes in my material, My brush doesn't paint. can you explain why is that?

@anonymous: The red dots are the vertices and appear if the mesh has been subdivided enough. For instance, if you use a cube and have not subdivided it, there will only be eight vertices, one at each corner. So in UDK, when you try to mesh paint, you will only see the dots appear on the corners. However, if you subdivide it a few times (4,6, or 8 times)  after you reimport it into UDK, then you should see those dots all over.


@juggulator: It's just a black and white version of the diffuse map.


@anonymous: Press & hold CTRL+Shift to paint.


I've also followed this step by step and it works fine up to the point of creating the instance material. None of the changes take effect on the mesh after creating the instance and assigning new textures. This might be a stupid question but, are we supposed to assign it to the mesh after creating the instance? I didn't see that part in the video. He just created the instance and started messing with the scalar parameters and it was changing. That didn't work for me. =\

Also, the parameters are changed around in the latest version (10907). The're not in the same order as in the video. I wonder if there isn't something different now that has to be done in order to get the instance to work?
