I can provide tailored folder structures or scripts to automate the compression process for your specific modding project. Share public link

Your PK3 placed sprites in the root directory instead of /sprites . Fix: Inside SLADE, create a folder named sprites . Drag all sprite lumps (S_START to S_END) into that folder. Delete the S_START/S_END markers—they are useless in PK3 format.
