Blender – Bake rigid body physics to Keyframes

Software:
Blender 2.79

  • I always forget this, try to do it through the regular animation baking option and get frustrated that it doesn’t work…

When you want to bake an object’s rigid body physics simulation to regular Keyframes:

  1. Select the wanted objects.
  2. In the 3D View Tools pane, In The Physics Tab, Press the Bake To Keyframes button.

Blender Cloth animation to Shape Keys

Software:
Blender 2.79

Steps for creating Shape Keys from cloth simulation: 

  1. Create an object with Cloth simulation.
  2. Give the Cloth Cache a name.
  3. Set Cloth cache to Disk Cache.
  4. Bake the Cloth animation.
  5. Move the time slider to wanted cloth state.
  6. Press the ‘Apply as Shape Key’ button on the Cloth modifier.
    * The cloth modifier will be deleted from the object.

  7. Apply new cloth settings to the object.
  8. Set Pinning to be the same Vertex Group if necessary.
  9. Give Cloth Cache the same name as before.
  10. Set Cloth cache to Disk Cache.
  11. Play the animation timeline so that the cache frames on disk will be loaded again.
  12. Repeat from step 5 for each cloth pose you want to turn to a shape key.

 

Reuse volumetric (smoke) simulation data in Blender

Software:
Blender 2.79

  1. Create a smoke simulation
  2. Set the Smoke Cache File Format to OpenVDB.
    * File must be saved for caching to be accessible.
  3. Set the Smoke Cache to External and choose the folder location.
  4. Cache the simulation.
  5. Create a new box object and make sure it has the same proportions as the original Smoke Domain box object.
  6. In the Physics tab, a Smoke Modifier to the new box, and set it to be a Smoke Domain.
    * make sure is has the same Divisions value in Resolution.
  7. For the new Smoke Domain, Set the Smoke Cache File Format to OpenVDB.
  8. For the new Smoke Domain, Set the Smoke Cache to External and choose the same folder location as the cache for the original Smoke Domain.
