So I’ve never once been able to rebuild any of my lighting in any project I’ve ever created. I’ve experienced the same issue even on new installs of windows and fresh installs of UDK4.
I’ve found that all over the internet people are having problems relocating the cache location and mine is actually set in a location that is writable and there is no straight forward explanation for a work around.
All my graphics cards are up to date and yet I still get crashes when I build lighting or even build anything.
Will there be an update for this issue in the next patch?
