Hi,
Every time I build the lighting in 4.2, I get an error stating that Lightmass cannot be run due to an incompatibility with 64-bit windows.
It is a brand new installation of Windows 7… with only Unreal Engine on it built purely for Unreal Development!
I am a bit pee’d off, to say the least… I only built the machine because I was tired of the constant crashing using 4.1 on my iMac, and thought the PC version might be more stable!
Anyway, moan over!
