Improved Editor Stability and Quality of Life
This was a really big focus for Unreal Engine 4.8. With every Unreal Engine release we fix hundreds of bugs and add many new features, but with Unreal Engine 4.8 we've worked hard to improve editor and game stability, as well as to address many of the most common engine bugs and small feature requests. We hope that the result is a very solid engine runtime and editor, and we'll continue to make stability a big focus of future releases.
New: SteamVR/HTC Vive Support
Unreal Engine now has comprehensive support for Valve's SteamVR API and HTC Vive hardware!
-All HTC Vive motion controller features are supported, and controller buttons/touchpads are bindable
-Full support for both room scale and seated experiences.
New: Playstation 4 Morpheus VR with 120Hz Reprojection
The latest Sony Morpheus hardware is now supported, along with support for 120Hz rendering using temporal reprojection.
-3D audio playback in VR has also been greatly improved for this release.
New: Landscape Grass Renderer
The new grass system dynamically renders instanced grass and other ground clutter meshes on the landscape around the player.
-Artists author grass density through the landscape material, by outputting density to a Landscape Grass Output node. This allows the grass placement to match the terrain texturing!
-Grass instances are procedurally generated by a background task according to the grass density map.
-Grass is efficiently rendered using a hierarchical instancing system that implements culling while keeping draw calls to a minimum. LOD transitions are per-pixel and fairly seamless due to Temporal AA.
-See the "Landscape Grass Tools" section below for information about how to set this up!
New: Hierarchical Level-Of-Detail System
This new Hierarchical LOD feature automatically creates LODs for groups of meshes! This greatly reduces draw calls and polygon counts when they are visible from a distance. This is great for open world games!
-To use Hierarchical LOD, set Enable Hierarchical LOD System to be true in World Settings. Once enabled, you'll be able to edit settings in the LODSystem section.
-Individual Actors can opt out by disabling their Enable Auto LOD Generation option.
-LOD meshes are generated as part of the 'Level Build' process, or by selecting Build LODs in the Build menu.
New: Procedural Foliage Generator (Experimental)
There is a new experimental feature for procedurally generating huge (or tiny, or medium-sized) regions of foliage instances quickly.
-Foliage Type assets now have properties to customize how they spread and grow over the course of a simulation.
-Multiple procedural foliage types can be simulated alongside one another to generate the foundations of an entire forest!
New: High Quality Depth of Field and Tone Mapping
-High performance DOF technique with circle bokeh and nice transitions from in to out of focus
-Circle DOF controlled by physical camera parameters: fstop, focal length, focal distance
-Supports a distance based blur to simulate light scattering through the atmosphere
New film like color and tone response
-Matches the Academy Color Encoding System (ACES) (http://www.oscars.org/science-technology/sci-tech-projects/aces)
-Added additional color grading and white balance.
-Baked into 32x32x32 LUT so it is 50% faster than before.
-r.TonemapperFilm 1 to enable
New: Redesigned Foliage Editor
The foliage editor has recently undergone a redesign! Besides improved usability, the new layout gives you the ability to more easily work with a large number of foliage types in the palette at once.
-Foliage thumbnails have buttons for toggling visibility and saving the asset, as well as the total instance count.
-You can now activate or deactivate multiple foliage types at once with multi-select.
New: Screen-Space Reflections for Translucent Surfaces
Translucent surfaces can now dynamically reflect other objects on the screen!
-Enable on translucent materials with the 'Screen space reflections' option
New: Landscape Grass Tools
New editor features have been added for setting up instanced meshes for the grass rendering system.
-A grass density map is generated from the landscape's material. A Landscape Grass Output node should be added to your landscape material, and one or more Landscape Grass Type assets can be assigned. For each grass type, a new input connection will appear, which is used to specify the grass density.
-Connecting a Landscape Layer Sample node directly will allow a landscape layer to specify the grass density. You can also connect a network of nodes to create more complex placement rules such as automatically removing grass based on surface normal or altitude or using multiple landscape layers.
New: Motion Blur and Anti-aliasing for Vertex Animation Materials
Materials that animate vertices using World Position Offset can now output accurate motion vectors. The motion vectors allow per-pixel motion blur from the procedural animation. Additionally Temporal Anti-Aliasing and Distance Field Ambient Occlusion can correctly reproject to prevent undesirable blurring.
Visualization of per-pixel velocities from a tree animated with World Position Offset.
-You can disable the feature per-material with the setting 'Support accurate velocities from Vertex Deformation'
-The Speedtree wind node needs 'Accurate Wind Velocities' to be enabled
-Note that this feature can only support velocities from changing time, not parameters set by blueprint or gameplay code.
