October 2011 UDK Beta Upgrade Notes
iOS

God rays and shadows support added on iOS


Facebook
Added dialog support for creating wall posts
Added friends list download support
Added support to request additional permissions from a user
Input changes
Added support for tilt/touch outside of MobilePlayerInput, moved support up to Input/PlayerInput (MobileInputZone handling is still in MobilePlayerInput)
Added Kismet events for generic key/axis input (for key presses and mouse/tilt)
Added a new Kismet event for touch handling
SeqEvent_MobileMotion/MobileRawInput still work, but they are now marked with [Old]
Added aTouch and aBackTouch axes to PlayerInput.uc, so script code can get touch events easily
Foliage Settings Paint Tool



Added a new paint tool for applying settings to foliage quickly and easily!
The following foliage settings can be painted:
Slope alignment, randomized angle and scale settings
Cull instances based new on slope, height or landscape layer criteria
Minimum radius between foliage instances
General density of foliage instances (add new foliage, or thin out areas)
New Unreal Landscape and Foliage Features

Paint tool: Added feature to paint layer weights to a certain fixed weight amount, with stroke history to handle falloff for overlapping strokes
Flatten tool: Changed behavior for painting layers to be the same as when painting heights
Noise tool: Added painting to a specified noise value and scale
LandscapeLayerBlend node now supports order-independent height-based blends between layers
Added dialog to the move-to-level tool to allow the user to move shared resources (material, layers) out of the persistent level into a shared package
Prevented painting on landscapes in locked and hidden levels
Component tool now considers brush size
Added a landscape info panel to UI, with component count, size, etc.
