Vertex painting on Terrain?

zombie420

I've just started playing around with terrain for the first time but I would like to get some interesting weather effects going. Is it possible to give my terrain materials a height map and paint things like snow over the terrain, or does terrain not support vertex painting like a mesh does?

It has weightmaps that you can paint with, but I don't believe they are vertex bound, and it's all under the hood. I can't recall the landscape interface atm, but it's as straight forward as adding a new material to the terrain layer palette which you can paint it on/off directly...no messing with vertexcolor driven lerps in the material editor or anything.
The documentation on UDN should explain the basics.

As far as I know, the Terrain and Landscape tools have their own method of texturing. They function like Vertex Painting, but it isn't actually Vertex Painting. It's just kind of blending the textures based on your brush settings for opacity. I don't think Vertex Painting works on anything but meshes...

Edit: Also, I can't remember which tool is which, but one of them using multiple Terrain Material materials that you create individually, but the other can use one material that has a variety of different textures assigned. I don't remember the setup though. I think Wenda on Youtube has a good UDK landscape tutorial.
