I’m having the same problem on my MAC, Unreal 4.7.3. Stuck on 50% encoding textures.
No matter what I do, every time I click ‘Build’ it re-builds the lighting and re-encodes the textures, which at times looks like it will take hours (literally).
Is there any way I can see the output of these processes ?
And why aren’t the results cached ? Why are they done over and over ?
