Here's a debugging function available from the OpenFlight loader that shows
what I think you're asking for ... you can call it if you want:

-----------------------------------
void
mgDumpGState ( pfGeoState* gstate )
{
    unsigned inh = pfGetGStateInherit( gstate );
    pfMaterial* mtl = pfGetGStateAttr( gstate, PFSTATE_FRONTMTL );
    pfTexEnv* tenv = pfGetGStateAttr( gstate, PFSTATE_TEXENV );
    pfTexture* tex = pfGetGStateAttr( gstate, PFSTATE_TEXTURE );

    pfNotify( PFNFY_DEBUG, PFNFY_MORE, " geostate: %p", gstate );
    pfNotify( PFNFY_DEBUG, PFNFY_MORE, " material: %p, inherited: %d",
                mtl, inh & PFSTATE_FRONTMTL );
    pfNotify( PFNFY_DEBUG, PFNFY_MORE, " texenv: %p, inherited: %d",
                tenv, inh & PFSTATE_TEXENV );
    pfNotify( PFNFY_DEBUG, PFNFY_MORE, " texture: %p, inherited: %d",
                tex, inh & PFSTATE_TEXTURE );
    if ( tex )
    {
        pfNotify( PFNFY_DEBUG, PFNFY_MORE, " name: %s",
                  pfGetTexName( tex ) );
    }
}
-----------------------------------

Regards.
