How to change page material directly

Hi,

I need change terrain material, but very fast(on each frame) because I want to set "depth" material for render a depth map to be used in water...

I've tryied with mRendereableManager->getRenderable()->setMapMaterial but anything happens :S, any ideas?

thanks.

I think it not so hard :

1) you should get material page names (something like mSceneMgr->getOptions("MaterialPageName", ...), You'll find that on the forum and/or in source files)

2) you should rewrite terrain material to have a great shader that can take in account your depth map and some custom parameters

3) Instead of "changing the material" on each frame, you can pass some shaders parameters like a depth map, and other things you need

But in this way, you have a "global" material, and maybe your changes on the terrain are local, so you may search on "projective decal" or something like that
Good luck!

(plz let us know if it works or not, and explain globally your feature result;))

Finally I've used a second technique with "Depth" scheme, I think it's the easier way to do this.
It works perfectly!
