Is anyone aware of any tutorials or guides on using the output of Mocha’s 3d camera solver in Houdini? In my case, I’ve gotten a moderately good solve. When I bring the fbx file into Houdini, aside from everything being very far apart, the camera view doesn’t seem right. I attached some spheres to each of the nulls, so that I could see them, but the view through Houdini’s camera was much narrower than the view in my scene. I could adjust the focal length to get something closer to my scene, but I’m not sure how I would line that up accurately. For example, the output of Fusion’s 3d camera tracker includes a plane attached to the camera that can be textured with the original footage to see how things fit together.
I’ve only gotten decent output from the 3d solver once, and in this case, there were two walls, and a floor, all with tracking markers on them. My other attempts seem to usually just result in a bunch of seemingly randomly positioned nulls, and a camera that moves wildly.
