What's new:

• Added SpawnThreshold parameter for particle systems (spawn rate for 'random' and 'spark' emitters depends on the speed of parent objects).
• Separate axis flip for particles: 'variation_x' and 'variation_y' parameters (run upgrade.py script for data upgrade).
• Shared 2D reflections (the same way as cube reflections are shared).
• New BodyWater for physical simulation of shallow water with two-way interaction.
• Access to floating objects in PhysicalWater.
• PhysicalWater and BodyWater spawn spark particles on contact, if particle system is made a child node.
• Emitters of child particle systems are synchronously enabled when the parent emitter is enabled.
• Continuous collision detection for spheres vs convex hulls, spheres vs meshes, capsules vs convex hulls and capsules vs meshes.
• Less memory allocations by render.
• Added two more flags for nodes: isVisible (the node was shown in a viewport) and isShadow (the node casted shadow).
• Added camera limitations for PlayerSpectator.
• Per-object freeze speed of physical objects.
• Inverse kinematics for ragdolls.
• Added more physical cloth samples, including ones of attaching the cloth to skinned mesh.
• Added BodyWater samples.
• Added inverse kinematics samples.
• Visualization of full ragdoll hierarchy and bone hierarchy in UnigineEditor.
• Reduced memory consumption by plugins for 3D editors.
• Fixed MeshSkinnedImport plugin for 3ds Max.
• Updated Softimage plugins (usability improvements).
• Added documentation on grass ("Principles of Operation / Objects / Grass" section of the manual).

API changes:

• engine.world.addVisibleNode() is renamed into engine.world.addUpdateNode().
• engine.world.getNodes() is renamed into engine.world.getIntersectionNodes().
• engine.world.getObjects() is renamed into engine.world.getIntersectionObjects().
