Obi is an advanced cloth simulator for Unity that uses particle physics to deliver high-quality, flexible and easy to use cloth simulation.

Available for Windows, Mac, iOS and Android.

Features: 
- Support for skinned meshes: unified solution for character clothing and regular cloth.
- Two-way rigid body interaction.
- Modular solver: don't waste performance, only use the constraints your cloth needs.
- Per module adjustable solver iteration count.
- Cloth proxies: drive high resolution meshes using low-res simulations. Works with skinned meshes too! - Softbody physics trough volume constraints.
- Independent stretch and bend constraints.
- Cloth is attachable to rigid bodies.
- Cloth can collide with itself and other cloth pieces.
- Physically based aerodynamics model.
- In-editor simulation preview.
- Easy-to-use integrated editor tools: selection, brush selection

unity液体系统Obi Fluid 4.1

With Obi Fluid you can create fully multi-threaded AAA quality fluid simulations with ease. Fluids react to each other, can affect and be affected by rigid bodies (even make them float or   sink!), and are capable of sticking to surfaces.

Please note that fluid simulation is a very intensive task. Be aware of its performance implications before using it.

Available for Windows, Mac, iOS and Android.

What to use it for:
- Small scale fluid simulations
- 2D fluid game mechanics
- Dripping fluid
- Splash effects
What NOT to use it for:
- Large scale fluid simulations
- Pools, oceans, lakes, floods

All physical properties or   the fluid are adjustable: viscosity, density, surface tension, stickiness, vorticity...

Requires Unity 5.5.4 or  higher.
1.1.6 What's New:
- Unity's Timeline is supported.
- CPU optimizations are improved when multiple ob jects appear.
- Drawcall does not increase even if the scale is reversed.
- The convenience of the editor is improved.
- Many bugs are fixed.
