problem with depth

I can't get depth working

things far away are better visible than the one that are near (like the robot)

PS. The sword does not have the depth technique. Only the ground(terrain), robot, and grass has;

there is no smooth transition with the terrain

I've fixed it by adding ingame

mHydrax->getMaterialManager()->addDepthTechnique(
static_cast<Ogre::MaterialPtr>(Ogre::MaterialManager::getSingleton().getByName("terrain"))
->createTechnique());

instead of the material files.
The same way as for the grass, and it looks good now.


Do I have to do it in the code ? Can't it be in the materials ?
