NexusTK Resource Viewer for EPF and related files.
IntelliJ is recommended for development, but you should be able to build with just Maven: (mvn clean; mvn package)
mvn clean
mvn package- Output is stored in
target/
Run TKViewer with:
java -jar target/TKViewer-*.jar- File Structures
- Note: The tile structures are compressed with zlib in the CMP format - it must be inflated!
