Recent changes:

• Instancing of skinned and dynamic meshes.
• Much faster stereo rendering due to shadows optimization.
• Terrain speedup.
• Alpha-channel of specular textures is no longer responsible for reflections, it modulates specular power (glossiness) now.
• Square brush in TerrainEditor.
• Manager has been renamed to RenderManager.
• Adjustable number of splits for WorldLights.
• Fixed material preview bug.
• Fixed flickering of water reflections.
• Added initial angle and velocity scale for particles.
• Visualization of occulsion query primitives in UnigineEditor.
• Added terrain sample with unique texturing (terrain_01).
• Intersection masks, engine.world.getIntersection() functions get a mask as third parameter.
• New order of arguments for initialization: Engine::init(UNIGINE_VERSION,argc,argv,project,password), where 'password' is a password for encrypted file packs.
• Script and shader preprocessor accepts only angle brackets for #include directive.
• Warnings on unused variables and arrays in scripts.
• More verbose script interpreter output on errors, including file name and line number.

Some notes on instancing follows. There is a pool for 64 bones drawn in once, so there is a huge speedup on skinned meshes with simple skeletons. Cloned ObjectMeshDymamic are also instanced, they are drawn by 32 in a batch. Plus there are some performance improvements in instancing of static meshes.

Here are pics for today, particle-based fountains from our unannounced game:
