Cooker - LogDerivedDataCache:Error

At the end of the long cooking process I get the following error in the Output Log:

LogDerivedDataCache:Error: Could not save memory cache ?E:/UnrealProjects/xyz/DerivedDataCache/Boot.ddc?.

By that time it has already deleted all the cooked files again and I had to scroll up to find what went wrong.

So, anybody can help me find out what the problem actually is?

Hello ZeroComfort,

I have a couple questions to narrow down the issue you are experiencing.

  1. Have you deleted your Saved & Intermediate folders?
  2. Could you post the full log for your packaging?

Thanks!

Hi , thanks for replying!

I haven’t deleted those folders. And the Error I’ve posted seems to be the only blocking one in the entire log. Though I would have posted it if I hadn’t worked it out already:

Now, I’ve managed to fix this issue myself after digging around, because I thought the DerivedDataCache location was a bit weird with those question marks surrounding it. After looking at this I figured that it might fail because the quotes were replaced with question marks (for some weird unknown reason), so I replaced them with quotes and now it seems to cook just fine.
