I'm facing actually the same problem on a sample app i'm doing.
Everything is okay, the indicator works perfect, the 3d model shows on the geoLocation, but is totally impossible to me, get closer to the 3d model, or even go around the model, and see it from different angles, it's always in front of me, and seeing at same direction, i mean: i loaded 3d batman, and it spawns looking to the right side, and i can't never see his face, or even get closer to him.
What is happening? Is not supposed that the 3d model is placed on that spot, and depending on if you come closer, or go around it, you could analyze the model?
Using cordova plugin.
