The first drop down set of fields labeled Description in this section are for the automatic creation of the UTCustomChar.ini file which will be needed to load any new character into Unreal Tournament 3. This process should be entirely automated unless your scene has more than one object of a particular PART_ID. More information can be found in the forums at Epic Games.

Denrei Window can help with the organization of a scene set up to create normal maps between high and low resolution character meshes. The set up relies on display layers to dictate which meshes are high and which are low resolution objects, and can then help you quickly build exported geometry in a way Unreal likes. At the moment, only ActorX is supported as an exporter, but Denrei took great pains to make sure that other exporters for other games could be added easily to Denrei Window in the future. Please let him know if you have any specific requests.

The first thing you'll need to do to use the modeling tools is allow Denrei Window to initialize the scene. This involves creating the display layers it needs as well as some helper locators which dictate the position of the various meshes in the scene. Go ahead and click the initialize button. Also check out the starter scenes available in the downloads section. These scenes come with prepared skeletons compatible with Unreal Tournament 3, and bound meshes which can be used as source for your own vertex weighting. Very helpful.

Any layer with a "_" preceding it's name marks that the layer contents are generated automatically and are not to be hand edited. Things in these layers get deleted and recreated frequently, so be warned. The created layers are as follows:

  • scrapLayer - Keep whatever you like in here. Denrei keeps this layer hidden during normal work. This is where the locator objects are placed by default.
  • lowResWorkLayer - This is the geometry which will end up getting exported. Keep objects here with names such as "Arms_01", "Head_02" and so forth. These names will be used during export to name the UPK files.
  • _highResProxyLayer - These meshes are created using the HighResMeshes button in Denrei Window. You may select individual meshes from the highResWorkLayer, or you may use the entire contents of highResWorkLayer by having nothing selected.
  • _bakeLayer - Automatically generated meshes which are triangulated and used as target meshes for the normal map baking operations. The contents of _highResProxyLayer are used as source objects.
  • _exportLayer - Automatically generated meshes which are properly triangulated, repositioned, bound to the skeleton using the meshes in weightSourceLayer as source. These meshes are the ones which will actually be exported by the Run ActorX button.
