Question

Log below shows that several resources that do indeed exist in game refuse to load. Could my Pak file be exported incorrectly or not readable? Unfortunately I can’t find much info on best practices or tweaks for exporting. I also can’t find anything in the log that sounds to me like it would be a big indicator as to

This used to happen to me in 4.3 when I was opening a project for the first time, maybe importing them again would help.

I tried reimporting the mouse cursor to see if it would eliminate at least that error from the list and it still shows up as failing to load in the log.

I’ve also tried tweaking export settings to embed and not embed .pck, exporting as debug, exporting as release, exporting with and without RCEdit… Nothing is putting a dent in this as far as the Export menu from what I see.

I have figured it out! I had my settings as:
Resources > Export Mode > Export all files except those selected
and I was treating it like Export files selected.

TLDR: If you have a bunch of files or resources in your exported project that just refuse to show up that you KNOW are there, check the verbiage of the Resource > Export Mode option to make sure you didn’t set it backwards.
Beyond that, do what @Mahan did and reimport real quick.
