***OBSOLETE***
New version is available on the Asset Store
Tested with unity 5.3.5, 5.6, 2017.x, 2018.x, 2019.1
***Does NOT work with SRPs (both HDRP and URP are not supported, for now)***
Dramatically reduces the number of polygons and drawcalls in your scene by converting 3D objects into 2D sprites(imposters) at runtime without any preprocessing.
Imposters are very similar to billboards, but imposters look exactly like original objects, while billboards are noticeably different.
System combines imposters in one mesh, so they will be drawn in one drawcall!
Source code included.
Unique features:
- Multiple cameras support (VR - visit forum!)
- Working with non-static objects
- Load distribution (no freezes)
- Powerful LOD system
- Runtime atlasing & mesh combining
- Smooth imposters transition (fading)
Other features:
- Fully REALTIME system
- Simple setup
- Increases 20x FPS
- Imposter Shadow Casting (new)

- improved imposter fading: now based on pixel screen position
- UpdateBehavior of imposters
Fixes:
- critical internal bugs are fixed
- fixed shadow distance when render shadows to imposter texture
- deleting mesh when deleting atlas
- deleting atlas when it is empty
- deleting BillboadTexture when atlas is deleted
- max atlas resolution up to 4096
- fix example scenes and new UI settings
