Today Epic Games sent out an email to an unknown amount of people on the Developer Mailing list, who now have access to the PS3 Mod Tools patch for there Unreal Editor.
They have been ask not to "distribute it or make it generally available to the public." So we will be giving you the best information without giving you the tools!
Update: So we have an update, there is some information now out that tells exactly what is and what is not supported for the PS3 Modifications. Below I have provided the exact wording that is included.
What Is Supported
The following types of mods are supported. See the Not Supported section for any restrictions.
Maps
These mods are created and saved with UnrealEd.. These are new maps that are intended for Epic supplied game types, or for your own game types.
Mutators
These mods are programmed with UnrealScript. These can be activated optionally during matches. These can range from replacing all weapons to changing gravity in odd ways to affecting player movement. These can be auto-downloaded from a server running the new game type without needing to install the mod on the client PS3s.
Note that this is just to play as a client; to run a server (or offline) with the mutator, you will need to install the mod the standard way. Auto-downloaded mods are put into a temporary cache only.
Game types
These mods are programmed with UnrealScript. This is a new set of game rules that use existing maps (see Total Conversions for game types) These can be auto-downloaded like a mutator, above.
Custom Characters
Character pieces are simply building blocks for the custom character system in UT3
Total Conversions
A Total Conversion, or TC, typically means replacing all of the content that shipped with a game with completely unique content, including the main menu.
On the PS3, the main menu cannot be replaced, but it can be used to load another level that is the TC’s main menu. This can then branch off to load the TC’s maps, etc.
These are generally a combination of new game types, new models, and new levels.
Other modifications may work, but these are what we have tested and planned for.
What Is Not Supported
Naturally, given the limited memory on PS3, etc, there are limitations to what you can do.
Mutators and game types must consist of UnrealScript code only. This means that you cannot have a mutator that turns all UT3 weapons into a space cow model that you import.
This is because they need to work with shipping maps, and too much content added on will cause the PS3 to run out of memory.
Importing sounds is not supported. This is because UT3 uses a proprietary version of ATRAC3 and we are unable to release the tool that is needed to convert .wav files to the format required by the game.
It is unknown if we will be able to have some system for sound conversion in the future.
We understand the limitation this places on mod developers, and will rectify this if at all possible in a future version.
