Hi @Rage, I think this question is related to the another topic you posted, so I will not explain again how import/export works in CInema 4D.
In your case, you have to use FBXEXPORT_TRIANGULATE and not FBXEXPORT_TRIANGULATE_GEOMETRY.
And yes you are right, currently, no symbol is defined for the FBX exporter so you have to use 1026370 directly.
Cheers,
Maxime.
