I’ve read epic’s documentation about setting up ChunkDownloader and I watched their video on youtube, It turned out that chunk downloader doesn’t support the new option of UseIoStore and it cannot mount .ucas and .utoc files except .pak file.
Please if you could help me with this, I was struggling for hours to solve this issue and cannot find any document online for solving this!
I think I’ve mostly solved the problem, you don’t need to manually mount .ucas and .utoc files! because they are mounted automatically once you have downloaded them using “ChunkDownloader” plugin as long as they have their corresponding pak file exist in the same folder,
Put in your mind that if you don’t want modding for your game, setup custom encryption keys in the metadata folder (I think) , so The only think that I am sure with is that utoc and ucas files are automatically been mounted, and I will leave this question open for anyone to ask
