I’m also attempting this.
Loosely following this workflow here: https://www.senseofspace.io/sense-xr-studio-depthkit-workflow
Currently trying to import the obj sequence in blender using Stop-Motion-OBJ (GitHub - neverhood311/Stop-motion-OBJ: A Blender add-on for importing a sequence of OBJ meshes as frames), then baking the sequence using the plugins tool and exporting as alembic. I’m importing into Unreal as a geometry cache.
It’s sort of working. I have a 70 frame animation, when I import the alembic in Unreal I get 70 separate 1 frame animations rather than a single 70 frame animation. That’s where I’m stuck at the moment. Any ideas? Maybe we can figure this out together.
