### [IMPORTANT] Obi 7 is a major update. If you're updating from an older version, it will require you to redo the setup most of your existing Obi-related functionality. It is recommended to use Obi 7 on new projects only, or if you must update an existing one, plan accordingly and set aside some time to perform the update.

# Change Log

All notable changes to “Obi - Advanced cloth for Unity” will be documented in this file.

## [7.0.5]

## Fixed

- Memory leak in ObiParticleStitcher.

- InvalidOperationException in Burst backend when having simulateWhenInvisible = false and solver not seen by any camera.

- NullRefException when instantiating a ObiTearableCloth with a disabled ObiTearableClothRenderer component.

## [7.0.4]

### Fixed

- Blueprint rotation parameter wasn't making any actual effect on blueprint generation.

- Property painting in the blueprint editor didn't work correctly with blueprint rotation values other than zero.

- Bug in skinned cloth that caused index out of bounds exception when having less bone influences than particle influences in specific situations.

- Bug that caused inactive particles to still be rendered by ObiInstancedParticleRenderer.

- Blueprint particle property texture export not working sometimes (due to GL.LoadOrtho bug in Unity)

- Bug that preventing pin constraints' break threshold from working when using the Compute backend.

## [7.0.3]

### Added

- Object layer support for all renderers.

- New "Synchronous Fixed" solver synchronization mode, similar to Obi 6, offers tighter integration with rigidbody physics.

### Fixed

- Bug in skinned cloth that caused index out of bounds exception when having less bone influences than particle influences in specific situations.

## [7.0.2]

### Fixed

- Solvers not placed at the scene origin would result in actors having incorrect motion blur in HDRP.

- Fixed issue when disabling all solvers and colliders simultaneously: ipon re-enabling them, the colliders would be ignored.

## [7.0.1]

### Added

- Render layer mask support to all cloth renderers and particle renderers.

### Fixed

- Having a ObiParticleRenderer with no material applied resulted in a exception in builds due GetInstanceID() returning 0 in editor but raising a nullref exception in the build.

## [7.0]

### Added

- Compute shader based GPU solver backend.

- Support for automatic decimation in all cloth blueprints.

- Support for non-manifold meshes in cloth blueprints.

- Greatly simplified cloth proxy system.

- More efficient solver update cycle, that also removes the need to have ObiUpdater components.

### Changed

- Rendering system is now fully multithreaded, integrated with the solver backend in use.

### Removed

- Native library based 'Oni' solver backend.

- ObiUpdater and all derived classes have been removed.
