1. Open the "exporting_motion_start.ma" in Maya.
2. Select the "Original_Camera" in the outliner.
3. Then enable "pass2obm" from the command line.
4. Save the resulting camera motion file to your curves directory.
5. For object motion, be sure and export their motion separate from the cameras. In this example, select the the cube1 and cube2 cubes and again enable "pass2obm" and save your resulting file.
4. Launch AE, and open the "obm_2_ae_start.aep" project.
This project already has a background image as a proxy that was rendered from EI. It also has ground, screen, and cube objects built from planes in AE to help speed things along.
5. Launch the MoCon script panel by going to the File menu, scripts and the 3DM_MoCon script file.
6. Select your comp window where the layers are like it is above, then select the "OBM Camera Import" button.
7. Select your camera file you exported from EI.
8. A success window comes up.
9. You should see the planes and cubes that were created for you in the inital project now. They have grids on them. The cubes are set at 0,0,0, so they are not yet in the proper location...
10. Now, import the cube object motion file too. This adds solids with the motion and names of the cubes. Note that their anchor point is at the bottom of the solid. This is handy, if you need to scale them to be man sized and to position on the ground. If you are using object motion for objects that fly, you might want the anchor point in the center of the object.
11. Select your cube1 and cube 2 solids and press U, and then U fast. This shows what has been keyed. Copy those channels, then paste them to the Cube1 and Cube2 nulls that were already create for you.
12. Scrub through the comp and you can see the camera and object motion was brought across successfully.
