I tried packaging my project and in the end it says BUILD FAILED and some errors above it.
Please help me as soon as possible I really need to fix it quickly.
Here is the log: Dropbox - MyProject.txt - Simplify your life
The log seems to indicate numerous errors:
Failure - 12 error(s), 1371 warning(s)
These include blueprints for the Mixamo characters you’re using referencing input axes that haven’t been defined in the project settings and numerous missing asset files (have you been deleting files in Explorer rather than through the editor?).
These issues seem to be halting the packaging process.
How can I see which assets files are missing?
And I think I’ve might been deleting some files in the Explorer…
Any ideas on where should I begin? I feel very lost here 
Thanks.
It lists all of them in the log (although multiple times, as your log file lists several attempts at packaging the project). You can search for the appropriate lines by hitting CTRL-F and typing “error loading” as the search query. If you’re able to replace the missing .uasset files and folders then that’ll fix it. If not, you could try right-clicking the Content folder in the Content Browser and hitting “Fix up redirectors.” Your mileage may vary with that second solution.
To avoid similar issues in future, don’t delete or move files within your project folder in Explorer; always do it from the Content Browser and do “Fix up redirectors” after any major folder reorganisation.
Hi Sntfon100,
In addition to what you’ve already discussed with Interference above… When you look at log and see that you have an “AutomationTool error,” press Cntrl + F and search for Error Summary. The first items listed as errors are typically (almost always) the items that are causing your build to fail. In your case:
There are texture/material assets (listed a couple of times each) causing the build to fail. Likely if you fix the Raindrop texture, it will automatically fix the Raindrop Material that uses this texture. Some things that could be wrong with the texture are, wrong format, size not a power of 2, etc.
Eliminate the issues in the image, retry and search the same location for other issues that may cause your build to fail after these have been corrected (if any).
