Vertex Colors and Multiple UV Sets for Skeletal Meshes

(含骨架角色模型可使用頂點著色與多重UV組)

• Users can now import vertex colors with skeletal meshes and access them in materials.
• Works with both the FBX importer and the latest ActorX plug-in.
• Vertex colors only work for GPU-skinned meshes (for now).
• Up to four UV sets will be taken when importing a skeletal mesh.
• The skeletal mesh vertex buffer only uses the amount imported so as not to waste memory.

Bloom Improvements

(後製特效Bloom的強化)

• New properties: BloomThreshold, BloomTint and BloomScreenBlendThreshold
• Bloom blur kernels larger than 64 are now supported

Penumbra Scale

(半影區的幅度)

• This option is very useful when trying to remove shadow artifacts when using a low resolution lightmap.

Custom Normals with FBX

(使用FBX檔案格式自訂法線貼圖)

• FBX importer now supports custom vertex normals
• This is useful for 'combing' vertex normals on foliage, or when you need smooth lighting continuity between multiple meshes
• To use this, first export normals (and/or tangents) using the FBX exporter in your modeling program
• Next, enable the new 'Explicit Normals' option while importing the FBX file into UE3

New Tool for Visualizing Render Target Textures on the HUD

Multiple UVs for Skeletal Meshes

(含骨架模型可使用多重UV組)

• Up to four UV sets per skeletal mesh is supported
• Works with both the FBX importer and the latest ActorX plug-in
• You can access these texture coordinates in materials assigned to your skeletal mesh

Game Caster Virtual Camera

(設定遊戲內攝影機錄製畫面)

• Game Caster virtual camera support is ready to use

Auto Texture Reimport

(材質自動重新匯入)

• New 'Auto-Reimport Textures' feature that detects source art changes and re-imports automatically
• http://udn.epicgames.com/Three/ContentBlog.html#Automatically re-import textures

Other New Features and Improvements

• Major performance improvements, especially with shadows and animation
• New per-level post process chain will override the single per-game chain if set
• http://udn.epicgames.com/Three/ContentBlog.html#Per map post process chain.
• Added one-bounce GI even for areas outside the Lightmass importance volume
• Note that this is lower quality than bounced light within the volume
• Physical Material Masks for material instances now available in the editor.
• Support for Shader Model 2 and fallback materials has been removed
• Fallback materials will be automatically deleted
• Improved screen-space ambient occlusion with new 'AngleBasedSSAO' setting
• This will yield better quality with same sample count
• Improvements to skeletal mesh importing of 'alternate weight sets'
• This allows vertex data to be shared between different weighted character rigs
• The editor's Map Check tool will now also warn you about potential performance issues
• Various minor improvements to Scaleform GFx workflow
• Gamma correction has been disabled throughout the GFx pipeline in order to better match the output of Flash

UDKGame

• DM-Deck has been updated with some new engine features
• Added god rays, improved bloom, and a new sky!
• Angle-based SSAO is now enabled in UDKGame by default (improved SSAO quality)
• Made shield projectile-blocking consistent with the old behavior
• Various minor cleanups to PlayerController, PlayerReplicationInfo and Pawn classes
