I am trying to calibrate an OBJ of a very large structure (a large bridge in a city centre). Right now I am just trying to setup a rough perspective under the bridge as a sort of "pre-vis". The issue is MM seems to load 3D objects with a totally flat, isometric perspective and you can not manually position a camera to look - for example - inside a room or under an object with perspective. I rendered a perspective POV from the 3D model and tried calibrating points based on that. Once I have all 6 points lined up very accurately, the model just disappears. I should be looking under and down the length of the bridge model with the object going overhead and behind me.
Whats going on here? is this some sort of camera clipping issue if a model extends out past and behind the camera in MM?
A basic camera placement tool in MM would be really helpful to use 3D objects...
