Due to the matchmove camera is based on 3DE and Maya, so the first step is to export the camera that we got and import into houdini.
In Maya
1. Export camera as the Alembic file
Select Cache > Alembic Cache > Export All to Alembic >select the “World Space” >Export
The most important thing:
Make sure to add the “World Space” to the abc camera
2. Export the animation
- Select all the objects in group
- From the main menu bar, select Key > Bake Animation >
- Click Bake
In the Bake Simulation Options window, select the bake options you want to use. For example:
- Use the Bake To options to specify whether you want the animation baked to the BaseAnimation, or to a new layer.
- Set Baked layers to Remove Attributes if you want the selected object’s attributes removed from any associated layers after their animation is baked.Attention: When Baked layers is set to Remove Attributes, the selected object’s keys will be removed from any associated layer that is not muted. If your workflow is to use layers like takes, mute all layers with keys that you want to preserve before baking layers.
- Turn Smart Bake on if you do not need your result animation to have one key per frame
After baking, Export the same way as the camera(world space should also be applyed)
In Houdini
1. File ▸ Import ▸ Alembic Scene in the main menus to quickly set up an Alembic Archive object
2. Make sure the resolution is the same as the maya camera
add the camera background as the reference
3.Add a null to control the camera and the object
