Today’s adventure will be cloning my currently fully error-flag-free build to the newly released Unreal Engine 4.12.1 and seeing what breaks. I did not try it out with any of the preview builds this time, since those builds did not want to download properly for some reason (this must not have been just for me…my blog got a lot of recent hits to my posts about the Unreal Engine repeatedly failing to install, though that was relevant to an older version – the bit about making sure you run the launcher with administrative privileges is probably still valid). The release version (non-preview) installed without difficulty, so I’m about to give it a whirl!
UPDATE: Map check complete, zero errors zero warnings. Thank you, Epic, for making this one painless!
