LogCook: Error: Content is missing from cook. Source package referenced an object in target package but the target package was marked NeverCook or is not cookable for the target platform.

Same here.
In my case it is complaining about some Megascans assets.

如果你在【项目设置】中勾选了【烘焙时排除编辑器内容】，会导致这种情况的发生

BreakMaker · August 3, 2024, 7:28am

Did not fix it for me.
Does this mean that it only cooks the maps any referenced package within those maps?

AlexPfaffe · August 5, 2024, 11:21pm

Same problem here, when upgrading from 5.2 to 5.4 some assets report this error.
I am suspecting that they have old materials in them which may not be upgraded.

Don’t recommend cooking editor content, increases packaged size and packaging time.
Instead check the log for what material is throwing the error and what the target reference is, duplicate the target reference and move it into the plugin folder, replace the reference and all is fixed.

For the landmass plugin it has some material functions within those material functions are also internal functions that require reference replacement!

Hukha · August 15, 2024, 4:59pm

Same here. Unchecking ‘Exclude editor content when cooking’ fixes the cooking but then is cooking extra…

tongucci · August 19, 2024, 12:10pm

Same

我没勾选也有这种情况，UE5.4.3

qianawi · August 21, 2024, 1:32am

Thank you so much.
我的问题解决了

For everyone still having some issues:

Try looking in the log for the error and look where it says “Referenced object:” go to that referenced object and right click and press “Validate Assets and Dependencies”.

This should fix up any wrong references.

Hope this helps

AltairGamesLLC · September 3, 2024, 7:56pm

Right click on the folder and Validate Assets and Dependencies. This works. THanks.

Mukar · September 15, 2024, 4:56am

Idk about anyone else, but “Validate Assets and Dependencies” is not working for me. All problematic assets are also in Landmass. I’ve tried to Validate these assets and their dependencies to no avail. Heck, I even validated the entire Engine Content folder.

Alternate solution in case this didn’t work for someone!

The solution in this post did not work for me but the referenced target suggested in the solution was the source of the issue. I had to remove the referenced asset from use because it was an engine asset being used after I updated to 5.4.

My Solution - Remove engine asset from use.

A temporary fix that lets my package while I fix those engine assets.

robyrom · September 28, 2024, 1:14pm

Hi, I’m aptempting to reproduce your solution but my referenced error files are out of my main contents folder. I can’t find the error files by searching in content browser. How can I solve?

dangerousbob88 · September 30, 2024, 10:27pm

Just throwing this out there that I did that and added the

[CookSettings]
CookContentMissingSeverity=Warning

in my Default Editor in.

Not sure which worked but it was packaged.

This was after building a new 5.4 project from source and migrating my old one.

I am having issues with the game crashing when testing after packaging so while it packages it doesn’t “fix” anything. This seems specifically with the Quixel textures in 5.4 as I was not having this problem in 5.3

Any solutions would be helpful.

enigmatrixgame1 · October 22, 2024, 8:40am

5.4.4 has this issue too. The solution accepted as “solved” seems not work for me. For those who think your issue is solved, I must say, it’s a bug not happen every time you cook/package. So you may cook successfully once, but failed next time.

JustCDR · October 23, 2024, 2:01pm

what path is shown in your error message?
Maybe it’s something caused by plugin content or so.

EnigMatrixGames · October 30, 2024, 5:26am

Found solution for my case. When open the project by using UE5 editor, don’t open your asset with cook error(s). On this file’s context menu(RMB), find Asset Action | Load, click it. Then from context menu, find Save, click it. Then I can cook the project successfully.
