Hook into source code (Recast NavMesh generation)

Hi together,

i want to auto-create (tactical) waypoints during the recast knavish generation process. I have done that before in two other engines with recast so that part is fine.

Obviously i need to alter the sources of UE4 to achieve this. I am thinking about this roughly like this: I need data recast produces during the NavMesh creation process. So i would go to the sources to this place and there i would check if in my current game a processor exists wich could process the recast-intermediate-data (the processor would be written by me of course).

So what kind of “object” could that processor be and am i able to check from the source-code if such an object would exist?

I am more than happy to try to explain better what i need to know if needed.

Thanks,
