Hi all,

How can I 'unapply' a light model or a fog object? I use pfFog::apply()
to apply a fog object m_pFog to the whole scene like this:

  // Override off so that changes are accepted
  pfOverride(PFSTATE_FOG | PFSTATE_ENFOG, PF_OFF);
        
  // Change fog properties
  pfEnable(PFEN_FOG);
  m_pFog->apply();
        
  // Override on to apply changes
  pfOverride(PFSTATE_FOG | PFSTATE_ENFOG, PF_ON);

Now I would like to delete the fog object but calling
pfDelete(m_pFog) does not succeed since the fog object m_pFog is still
referenced by someone (reference count 1).

So how do I get the reference count to zero? There is no
pfFog::unapply(). I also thought that calling pfApplyFog(NULL) might
help but this function seems not to be available when using the C++ fog
API?

Thanks for any answers,
Yves
