Unity 5 optimized version available (just access the Asset Store from Unity 5) AssetStore Page And here is a webplayer of InstantOC 2 These are the new features of the 2.x release cycle, already there: - terrain occlusion culling - occludee support - lights occlusion culling - dynamic batching. Other stuff that will also be added in the 2.x release cycle: - code refactoring --> more modularity and extensibility, simple API - 4 LOD levels - easy setting for distance culling for LOD (it's already possible with a simple "trick") - dynamic load/unload of LOD levels from disk at runtime (like SmartLOD) - IOC Zones, to easily change IOCcam settings based on zones. For instance change the Rays Samples and Rays FOV when you go from an indoor area to an outdoor area or vice versa.
