Detailed Description

Describes the global blending factors for combining subsequent renders with the existing frame contents.

By default the operation is Ogre::SBO_ADD, which creates this equation

$$final = (passOutput * sourceFactor) + (frameBuffer * destFactor)$$

Each of the factors is specified as one of Ogre::SceneBlendFactor.

By setting a different Ogre::SceneBlendOperation you can achieve a different effect.
