I MoTracked a scene and got a 3D solved camera. Everything looks great except I want to add some physics to my scene. The solved camera does not have the same world orientation as the footage I shot, so physics will not act correctly for the footage.
Should I try to adjust the solved camera or can I change the orientation of my scene? How would I do either of those options?
You can turn off the master gravity in the project settings and then add your own gravity object (under particles in the simulate menu) and point that object Y in the opposite direction you want gravity to pull. Add a sim tag to the objects your want gravity to affect and add the gravity tag to the simtag's forceList area (make sure to set the force mode to "include")
I'm sure it's a bit of a pain to work at a funny angle anyway. There's probably a way to se the ground pland and orientation when tracking but maybe it's easier to just put your whole scene in a null object and and re align it however you want. As long as your tracking markers and camera are in the same master null you can orientate it however you want
