Hi all.
I have some problem with the Hydrax depth technique.
1) I attach a mesh to the SceneNode. Then I use the code like this
to add a depth technique.But it dosn't work!The part under the water is still can see when my camera is above.
I had change the material before,but it's the same.
Is that any requirements with the transparent texture?Can anyone give me a sample texture?
2) Using plsm2 + Hydrax.I've read this topic http://www.ogre3d.org/addonforums/viewtopic.php?f=20&t=9174. And I add the code to my program as Xavyiy said.
And nothing happened.At last, I found that the mat is allways NULL.
This is my terrain config file
Sorry for my pool english.
Thanks.

1) I attach a mesh to the SceneNode. Then I use the code like this
MaterialPtr mat = static_cast<Ogre::MaterialPtr>(Ogre::MaterialManager::getSingleton().getByName("CONO"));
mHydrax->getMaterialManager()->addDepthTextureTechnique(mat->createTechnique(), "TransparentTexture.png", "a");to add a depth technique.But it dosn't work!The part under the water is still can see when my camera is above.
