- The alembic format serves as a good way to bake mesh data with lots of modifiers
|
||
|
|
- This script will convert mesh animations to shapekeys. Digusting, but it just might work

|
|
- Enable the .mdd addon in blender to export as a mesh cache
|
||
|
|
- It might work as a direct export to .mdd, but I did alembic first, then rexported to mdd
|
||
|
|
- Create new object with same mesh and empty modifier stack and add a mesh cache modifier to load exported file.
