Can't package project for unknown cook failure

So I been working on a game for almost 2yrs now. I started it on v4.10 and can’t move it because some assets I’m using aren’t compatible with newer versions. But after I try to package the project to test it and see how it works on another computer I get the unknown cook failure. I have removed assets that I don’t use to see if it helps.

When I look at the log everything seems like it’s going fine, but once it hits the end…I get the red error. I asked in the forums but there wasn’t much info given to help. So that is why I am here hoping my hours of work isn’t a waste.

Here is a zip file of the most recent package attempt. I haven’t tried anything since this.

it seems like your S_LightError.uasset casuing an error

and this “0]LogInit:Display: LogPackageName:Error: DoesPackageExist: DoesPackageExist FAILED: ‘None’ is not a standard unreal filename or a long path name. Reason: Path should start with a ‘/’”

Thanks for the reply, I will look into it and see if I can fix the issue.

edit: So I can’t figure out how to fix the “0]LogInit:Display: LogPackageName:Error: DoesPackageExist: DoesPackageExist FAILED: ‘None’ is not a standard unreal filename or a long path name. Reason: Path should start with a ‘/’” do you have any advice how to start to look for this problem?

Try deleting your Intermediate, Saved and Config folder from your project. Keep in mind that deleting your Config folder will reset your configurations set for the project. Make sure you set those back up before packaging

So I did that, still got an unknown cook error. I have no idea what to do anymore. This is an updated log zip folder.

So I think I may have found the solution to my problem. I made a new FPS project and copied folders one by one from my main project and attempted to package the project and see what happens. I first imported the folder with all of my models that I made and it packaged successfully. So my models have no issues. But once I copied an asset pack I bought, it failed. I moved some meshes that I used and deleted the rest including materials, And it built with no problem. So I am guessing that either some or all the materials in that pack I bought are causing the problems. Hopefully I can find the best way around it and get my game finished. Wish me luck!!!
