Beyond the lesson
In this lesson you learned the fundamentals of the Live workflow.
We made numerous decisions for you regarding which points to track and how to improve the solution. With more practise, you will learn these decision-making skills. Additionally, you may want to review the section on “Shot Strategy” in the Maya Help.
In general, you can expect to run the solver several times to find a correct solution. Before each solve, make improvements by adding track points in a variety of places and by deleting regions from the track data if they are not accurate. Even if one track point is off alignment on one frame, it could result in an incorrect solution.
Your solution has the correct camera movement, but you may wonder why the camera and locators are placed below the perspective view grid. If you want to control where the solution is placed within the scene, you need to give the solver more information, called survey constraints. Continue with the next lesson to learn more.
Exporting and rendering solutions
With the camera movement solved, you can create your animation using the solved camera to make sure the animation does not move out of the camera view. If your animators use Maya Complete or another software product, you must export the camera solution from Live ( Scene > Export Scene As). You can also export to other 3rd party 3D and compositing applications.
When you render the animation, we recommend you do so without the image plane background. A better workflow is to render the animation created in Maya separately and then use a compositing software application to combine it with the live footage background.
However, if you do want to render the image plane, you must turn off the Use Cache option on the Setup control panel. The Use Cache option utilizes a Roto node, which does not render. By turning Use Cache off, Live switches to the standard Maya image plane, which is renderable.
