How to make TDU accept and use new files in Euro/Bnk folder ? (TDUF MappingTool steps)

1. Add those new files to TDU folders
2. Use TDUF Mapping Tool with list-missing operation to make sure all new files are detected : MappingTool list-missing --bnkDir "C:\Program Files(x86)\Test Drive Unlmited\Euro\Bnk"
3. Use TDUF Mapping Tool with fix-missing operation : MappingTool fix-missing --bnkDir "C:\Program Files(x86)\Test Drive Unlmited\Euro\Bnk"
4. Update TDU database resources (all language files) to contain all new filenames (with TDUMT/TDUF DatabaseTool)
5. Update TDU database topics to point previously created database resources for model, gauges, rims ... (with TDUF or installer)

How to make TDU accept a new file in Euro/Bnk folder ? (manual steps)

Every file has a checksum, computed value, based upon its relative location in Euro/Bnk folder. To allow TDU to load this file, an entry with right checksum must exist in Euro/Bnk/Bnk1.map file. To get this checksum, one has to apply CRC-32 algorith to file location. Used settings:

• Please note that location string should be relative to Euro/Bnk directory, lower-case; directory separator is the slash symbol /. e.g: vehicules/a4_dtm.bnk => 0x405b4ffa (1079726074)
• Initial value = -1
• Modifier, used to XOR value at the end = -1
• Polynomial used to generate hashing table: 0xedb88320

How to unlock a vehicle slot in database

• Change 'BitField' value in CarPhysics topic to 111.
• Also, make sure all other information is complete (resource links, physics etc).

How to add a vehicle slot in database

There's no tool for that, still.

• Add a new entry in CarPhysics topic with a 'VehicleId' value that does not exist.
• Ensure that 'BitField' value is set to 111.
• Also, make sure all other information is complete (resource links, physics etc).

Does a tutorial about adding new vehicles even exist ?

Yes, Tutorial: How add new car on TDU | turboduck forum

How to add a new brand with logos

Use TDUF. Otherwise, prefer using latest community patches with integrated brands and logos.

Note that logo count by design is limited to 63...
