So I've been trying to use the advanced patch editing options on my terrain patch just like I used to in world at war assuming it would work the same way. However when i hold alt and click on the terrain nothing happens, did they change the key bindings or something?

EDIT: Nevermind, turns out they slightly changed how you are supposed to do it. In waw I used to use it while in vertices mode but now you can't be inside vertices mode.

glad you figured it out, but for people with the problem needing help heres a little step by step tutorial

1. choose a texture
2. make it a terrain patch
3.copy and paste it
4.change the new patch you just pasted to a blend texture
5. press y
6.make sure alpha is selected
7. hold alt when hovering above the texture on the 3d view, you will notice little orange dots
8. with alt held click and move around

hopefully that helps ill be making a video of it today so its easier to see what im talking about
