Lights in ogre

Does ogre's lights supports map projection ?

You can attach a texture to a frustum and use it as a projection texture.

Code: Select all

MaterialPtr mat_caust = MaterialManager::getSingleton().getByName("Caustic");
    TextureUnitState* tus_caust = mat_caust->getTechnique(0)->getPass(0)->getTextureUnitState(0);
    tus_caust->setProjectiveTexturing(true, m_caustic_frustum); 

Now "Caustic" texture projected by m_caustic_frustum.

Thanks a lot for your fast answer, I use Map projection instead of create many spotlights ( rendertime :s ) ans it's very useful for me ...
