We recently upgraded a project from UE 5.1 to UE 5.3.2. Our total pak + ucas size for Windows Shipping builds used to be around 9GB after compression, now it’s around 15GB. We haven’t changed anything major when it comes to build settings, compression or other, but it seems from the file lists in both pak and ucas files that more or less every file is larger, often 3-5 times larger.
Are there any config changes or similar that changed from UE 5.1 to 5.3 that could cause something like this? We have looked over things like Oodle settings, packaging options (for UAT), texture group settings, etc, with no luck so far.
Any help would be greatly appreciated!
