UDK June Beta Released!

Eat 3D Blog

Epic have released the June update for UDK !

The update includes numerous bug fixes and new features, including FBX Custom Normals , Penumbra scale adjustment and Numerous skeletal mesh improvements Laughing out loud


Vertex Colors and Multiple UV Sets for Skeletal Meshes

  • 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


Penumbra Scale


Custom Normals with FBX

  • 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 UE3New Tool for Visualizing Render Target Textures on the HUD

Multiple UVs for Skeletal Meshes

  • 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 meshGame Caster Virtual Camera
  • Game Caster virtual camera support is ready to use

Auto Texture Reimport

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



  • 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
