I'm currently building the reach Falcon based on a max model I found on this site. I've successfully developed the .model_collision_geometry file for the vehicle, but when I go to make the .gbxmodel, I get this. Sapien won't create the falcon in game because it says OUT OF OBJECTS, no doubt due to this error. I did not draw the physical model itself, so any insight into what my problem might be would be greatly appreciated.

I get that all the time but it's never caused any issues. I'm sure that could cause some sort of problem, but that's not what is causing this. I'm not sure what exactly is causing the problem but my guess would be that your map exceeded the tag limit but I don't know.
