I can’t package my project:

Hi Fanto88,

Looks like the cook log shows that a file is corrupt??
[2015.02.14-14.21.21:550][ 0]LogLinker:Warning: The file ‘D:/Google Drive/1.5/Prigione/Content/Blueprints/Menu2.uasset’ contains unrecognizable data, check that it is of the expected type.

Does this file load correctly in the editor??
Are you able to get this file from source control / revert to an earlier version? This may fix the issue.

Thank you for the reply, MrFred.
I don’t know why but when i delete an asset on Unreal Engine editor he still search for that during the package. I will try to delete manually the .uasset from my project folder.

MrFred, thank you, really.

I solved the problem deleting all the .uasset that failed to compile from the project folder. But why deleting the object on UE doesn’t delete the .uasset in the folder?

If deleted through the unreal editor it should delete the file on disk also.
Perhaps the file is read only???
Or perhaps google drive is putting the file back because it thinks it shouldn’t be deleted???
If you discover this is because of google drive then would be really nice to fix this issue.
Internally we use perforce for source control and have integration for that.
We also have support for subversion.

Maybe you are right, I never thought about google drive sync as a problem. I will put more attention, thank you for your reply. Now i can package the project without any problem. Thank you,sir.

If you do find a good solution to this we would be interested to hear it as I’m sure other people are using google drive.

Regards
