- Description:
- Obi Softbody is a powerful tool for simulating complex elastoplastic softbodies in Unity. It uses a particle-based approach, where softbodies are represented by ellipsoidal particles held together by shape-matching constraints. This allows for realistic deformation and collision simulations.
The engine supports both CPU and GPU modes, with CPU mode requiring the Burst, Jobs, Collections, and Mathematics packages. GPU mode requires compute shader support.
Key features include:
* Advanced oriented-particle XPBD solver
* One-click softbody generation
* Ability to turn entire objects or specific parts of characters into softbodies
* Plastic deformation and recovery
* Unconditionally stable simulation
* Two-way rigid body interaction
* Modular solver with adjustable iteration count
* Support for all kinds of meshes, including non-manifold ones
* Self and inter-collisions
* Automatic camera culling
* Easily extensible and modular architecture
Note that Obi Softbody is not a clay/mesh sculpting tool and does not support topological changes in meshes such as cutting/tearing. - Technical Details:
