Downloaded the original, tried using winbspc but didn't work.
1. BSPTexRM via command line to remove custom textures from the map and get a trimmed version.
2. Run Half-LifeBSPTextureTools to get all textures from original map. Export to images and WAD
3. Run winbspc on trimmed version and convert to a map file.
4. Use J.A.C.K, *optional import WAD, Tools>Options>GameProfiles>Textures*
5. Save as .vmf
6. Convert all images via VTFEDIT, I converted entire folder.
7. Open CSGO SDK hammer and VMF file, remove and edit out map breaking bugs.
8. Compile and open log and go through every missing texture and replace with actual ones.
9. Work through the map, fix gameplay aspects that got broken and align textures.
10. Keep working on the map until happy and then publish on workshop.


I used prefab 6340 on gamebanana for timer as old timer didn't survive the port.


Feel free to ask questions and give feedback about the port.
