View Full Version : Vertex Painting in CE3?
Quite simply, I'm struggling to find any documentation on vertex painting on meshes in CE3 (which I have heard is available).
Like many people here I'm new to CE3 so I'd appreciate any information you can offer.

Vertex Painting can only be done in the DCC of your choice. You can't paint instances in the Engine.
If you're on Max, simply add a vertex paint modifier and start painting.
But for it to work in game, the material you are using needs to have "vertex colors" enable in the shader params.
Is it possible to assign different textures to the different vertex colours?
You mean blending textures? Yes, we have two systems for that, blend layer (that requires a heightmap for the mask) and the dirt layer.
Forgive me for possibly not making sense.
Is there any documentation on doing that?
For example, I have a rock, and I want to vertex paint moss on it - that's kind of what I want to know if CE3 is possible.

in the shader generation params, check the "blendlayer" OR the"Dirtlayer" box.
then in the texture maps field,
for the BlendLayer :
Custom > your 2nd diffuse map
 Custom > your 2nd normal map
Opacity > your blending mask
for the Dirtlayer :
Custom > your 2nd diffuse map (dirt map)
then according to which option you chose, you're gonna have different option to setup in your shader params.
Blending is controlled by the vertex alpha, painted in max/maya/etc, so don't forget to check the "vertex colors" box
Thanks guys, I'll have to test it out as it doesn't make 100% sense to me reading it, and i'll let you know!

In the forest level included in the free SDK, most of the buildings use one or both of these methods to add detail such as paint to wood.
Look through the material editor, see what settings are used and tweak them to see what they do. Also open up the relating textures to get a better idea of what's going on, take a peek at the alpha channels as well.

How would you paint vertex in Maya and export to CE3?
