Don’t forget, it’s easy and secure to obtain a commercial UDK license online. Our FAQ can help you determine which type of license is right for you.
This month’s beta release includes lots of upgrades, including:
- Numerous skeletal mesh improvements
- Improved bloom with added properties
- New HUD texture visualization tool
- FBX support for custom normals
- Penumbra scale adjustment in Lightmass
- Game Caster virtual camera support
Here’s the full list in detail:
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.
- New properties: BloomThreshold, BloomTint and BloomScreenBlendThreshold
- Bloom blur kernels larger than 64 are now supported
- This option is very useful when trying to remove shadow artifacts when using a low resolution lightmap.
- 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
- 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
- Game Caster virtual camera support is ready to use
Auto Texture Reimport
- New 'Auto-Reimport Textures' feature that detects source art changes and re-imports automatically
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
- 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
