How to do parallax mapping in UDK?

[riowahab]

Is there any ways to do it?
Please give some tutorial on it, I couldn't find any tutorial about it.
Thank you.

Use the bump offset node in the material editor.

Just plug a greyscale bump map into the height node and then connect the bump offset to all textures UV nodes. If you just have a diffuse texture, connect that. If you have a normal map too, connect the bump offset to both.

Well, it works with connecting to the Diffuse only, but it looks really crappy.
If you use both (and a decent heightmap) it works better and looks better ;)

Manual technic (more cpu calculs, calculc from two channel to get the third channel, its to get more place in the memory)

That explains parallax mapping in UDK. Th alpha on the normal map in the example is a gray scale height map. This height map is needed for all parallax mapping.

I was fiddling with this for AGES! Until I realised that my heightmap didn't have an alpha channel! XD

I just connected it up from the red channel and this is what I got,

Mmmm, bumpy dirt.
