Can't package project: Error unknown cook failure

Hello all!

I’m having this problem where I try to package my project I’ll get an unknown cook failure error. I’m stumped as to what the problem could be. Any help would be much appreciated.

I’ll post a screenshot of the output log.

Imgur

Thank you!

If I can read the red text correctly, it complains about the path / file name being too long.

That’s what I gathered as well. Any idea how to fix that?

I did think of that. The error you saw before is when I set the output to the desktop.

Change the output location to something with a shorted path

Try something very short like C:\

Tried that as well. same problem :confused:

Derek3d,

Could you please provide me the full log. If it comes down to how long the filename is, you’ll need to lower it to 256 or below in characters.

Thanks!

Sure! how would I post it? It’s quite long

Save it as a .txt file and upload it to your next response.

Thank you for your help.

Derek,

After reviewing your logs, I see that you have a lot of warnings/errors listed. The first thing I would try is to create a new project and see if you can get that project to package the same way and whether or not you run into errors. If you do run into errors on the new project then it’s suggested that you Verify your version of the engine through the Epic Games Launcher as you could be missing some files.

I would also suggest copying your project over to 4.10 and 4.11 and see if you run into the same errors on a newer version of the engine. Do not convert your project when moving it between versions of the engine. If you do, you can’t go back to 4.9 but creating a copy is different.

Please change the following names of these assets:
‘/Game/LeapMotionContent/materials/camera/Brownie/frontplate_trim_Inst (1)’
‘/Game/LeapMotionContent/materials/camera/Brownie/frontplate_trim_Inst_eyes (1)’
‘/Game/LeapMotionContent/materials/camera/Brownie/frontplate_trim_Inst__lens (1)’
‘/Game/LeapMotionContent/textures/gun/seamless_wood2_NRM (1)’
‘/Game/LeapMotionContent/UI/main/MainMenuLogo - Copy’
‘/Game/LeapMotionContent/UI/main/MainMenuUI_logo_Mat - Copy’
‘/Game/LeapMotionContent/UI/main/room_label - Copy’
‘/Game/materials/brain/jar_cap_Inst (1)’

Take out the special characters and the spaces from these assets, you shouldn’t run into these problems once you’ve done that.

Review the error messages along with these files as well and try to figure out what is causing this error. It could be that the blueprint is set up incorrectly, or something is missing from them.

After you’ve corrected all of these issues, please delete your Intermediate, Derived Data Cache and Saved folders from your project and try to package again.

Thanks!
