As announced at the Inter-Polar Conference the other dayWe are working on research and development of 3D simulations of glacial lake collapse floods. Among them, the Sony ELF-SR1 was used to show 3D simulations in 3D. As a result of testing the following 3 methods in order to stereoscopic display the 3D disaster simulation created with Blender on the Sony ELF-SR2, it worked as desired with the 3rd method, so I will keep a record of the method.

① Blender → Unity → ELF (convert the whole thing to Alembic)

steps:
- Convert entire Blender files to Alembic files
- Migrate to Unity and project

results:
- The projection itself is possible
- However, it becomes 20GB in a few seconds (around 200 frames) and simulation processing is not possible
- When migrating Alembic to Unity, it cannot be read properly if the file data is large
- There are cases where it was possible to read at around 10GB, so the file size seems to be an issue
- Due to verification in a PC environment with 16 GB of memory, it is unclear whether it will be solved with a higher spec PC

② Project directly from Blender

steps:
- Official pluginsUse (no updates since initial creation)
- Implemented in the recommended version of Blender 3.6
- Test with simple liquid simulations

results:
- Projection is possible
- However, simulated movements are not reflected on ELF
- Key animations are described as possible, but they don't work
- Only the movement of manually moved objects was reflected

③ Blender → Unity → ELF (split method) ✓ Success

steps:
- static model → export as FBX file
- Liquid simulation part only → Convert to Alembic file
- Integrated in Unity, and the key animation part where the bridge breaks was also created on Unity
- Projection to ELF

results:
- File size: just over 1GB
- ✓ Successful stereoscopic projection with ELF!
