void NL3D::CWaterPoolManager::setBlendFactor (  IDriver *  drv,
float  factor
) 
 

Set a blend factor for all pool (more precisely, all models based on a water shape) that have a blend texture for their envmap (to have cycle between night and day for example) NB : once this is called, textures are not released from memory because subsequent blends are expected to happend when transition has finished, one should call releaseBlendTexture to eventually release textures from system memory

Parameters:
factor The blend factor which range from 0 to 1
